3. A figure is made up of a rectangle and a semicircle as shown in the diagram below. what is the area of the figure?
Jawab:
Area itu bahasa inggris dari Luas, maka
Area of square = S x S
= 7 x 7
= 49 cm²
Radius = Diameter / 2
= 7 / 2
= 3.5 cm
Area of [tex]\frac{1}{2}[/tex] circle = [tex]\frac{1}{2}[/tex] x [tex]\pi[/tex] x r²
= [tex]\frac{1}{2}[/tex] x [tex]\frac{22}{7}[/tex] x 3.5²
= 19.25 cm²
Are of the figure = 49 + 19.25 = 68.25 cm²
Penjelasan:
phi [tex](\pi )[/tex] untuk [tex]\frac{22}{7}[/tex] digunakan apabila jari-jari/radius berkelipatan 7, sedangkan
phi untuk 3.14 digunakan apabila jari-jari/radius tidak berkelipatan 7

5. in the figure below BD=DE find the area of the shaded part
Answer:
1,728 cm²
Explanation with steps:
BD = DE = 1/2 x 96 cm = 48 cm
area of the shaded part = area of ABC - area of ADC
area of ABC
= 0.5 x AC x BE
= 0.5 x 72 cm x 96 cm
= 3,456 cm²
area of ADC
= 0.5 x AC x DE
= 0.5 x 72 cm x 48 cm
= 1,728 cm²
so the area of the shaded part is
= 3,456 cm² - 1,728 cm²
= 1,728 cm²

The area= luas yaa
okee berarti sangat gampang kpk!
Luas persegi panjang= lebar x panjang
maka panjang= 5 3/4 =23/4 cm dan lebar=3 cm
L= pxl
= 23/4 x 3
=69/4
=17 1/4 cm atau 17,25 cm
8. What is the area of the triangle shown below
a = 5
b = 5
c = 8
Keliling
= a + b + c
= 5 + 5 + 8
= 18
s = 1/2 x keliling
s = 1/2 x 18
s = 9
Luas
= √(s(s - a)(s - b)(s - c))
= √(9(9 - 5)(9 - 5)(9 - 8))
= √(9 x 4 x 4 x 1)
= √144
= 12 satuan luas
9. Look at the picture below. If the side of a small square is 2 cm, then what is the area of the figure?
2² x { L (1+2) + L (3+4) + L5 + L6 + L7
= 4 x { 3 + 2 + 3 + 4 + 6 }
= 4 x { 18 }
= 72 cm² ✔️
The area of the figure is 72 cm².

12. Find the area of the shaded part in the figure below
4. Area = 49.2075 m²
5. Area = 63.25 m²
Penjelasan/Explanation
Number 4
The area of that figure equals to the area of the square minus the area of the semicircle.
The length of each side: s = 9 mRadius of semicircle: r = ½sA = s² – ½Ï€r²
⇔ A = s² – ½Ï€(½s)²
⇔ A = s² – ½(¼Ï€s²)
⇔ A = s² – (1/8)Ï€s²
⇔ A = s²[1 – (1/8)Ï€]
⇔ A = 9²[1 – (1/8)×3.14]
⇔ A = 81(1 – 0.3925)
⇔ A = 81(0.6075)
⇔ A = 49.2075 m²
Number 5
The area of that figure equals to the sum of the area of the right-angled triangle and the area of the semicircle.
Base of triangle: b = 8 mHeight of triangle: h = 6 mRadius of semicircle: r = (½×10) m = 5 mA = ½bh + ½Ï€r²
⇔ A = ½(bh + Ï€r²)
⇔ A = ½(8×6 + 3.14×5²)
⇔ A = ½(48 + 3.14×25)
⇔ A = ½(48 + 78.5)
⇔ A = ½(126.5)
⇔ A = 63.25 m²
KESIMPULAN/CONLUSION4. Area = 49.2075 m²
5. Area = 63.25 m²
13. in the figure below BD=DE find the area of the shaded part
AREA

Solutions that match the question!
Solution :The area of the large triangle minus the area of the small triangle.
BD = DE = 1/2 BE = 1/2 96 = 48 cm
Area 1
= 1/2 × 72 × 96
= 72 × 48
= 3.456 cm²
Area 2
= 1/2 × 72 × 48
= 72 × 24
= 1.728 cm²
[tex]\\[/tex]
Area of the shaded part :
= Area 1 - Area 2
= 3.456 - 1.728
= 1.728 cm²[tex]{ \green{ \boxed{ \boxed{ \sf{ {Answer \: by : AdhidMagelang}}}}}}[/tex]
14. The figure is made up of a square and trapezium. The perimeter of the figure is 60 cm. Find the area of the figure. Use the steps.
Jawab:
The area of the figure is 188 cm².
Penjelasan dengan langkah-langkah:
Form that figure, we know that A and C are both squares. Therefore, the length of the rightmost side of the figure is 8 cm.
Let s be the length of C’s sides.
Given that the perimeter of the figure is 60 cm, we can get:
(14 + 2×8 + 3s) cm = 60 cm
⇔ 14 + 16 + 3s = 60
⇔ 30 + 3s = 60
⇔ 3s = 60 – 30
⇔ 3s = 30
⇔ s = 30/3
⇔ s = 10 cm
Let A be the area of the figure, we can find:
A = the sum of all areas
⇔ A = area of square A + area of trapezium
⇔ A = s² + ½(base+top)×height
⇔ A = 10² + ½(14+8)×8
⇔ A = 100 + 11×8
⇔ A = 100 + 88
⇔ A = 188 cm²
CONCLUSION∴ The area of the figure is 188 cm².
15. in the figure below,the value of x is.... cm
6 / 18 = x / x + 16
18x = 6x + 96
18x - 6x = 96
12x = 96
x = 96/12
x = 8
16. Find the perimeter and area of the composite figure below. BANTU PLISSS
perimeter = π x d + 12 + 12
perimeter = 3,14 x 12 + 12 + 12
perimeter = 37,68 + 24
perimeter = 61,68
Area = 12 x 12 - π x r x r

19. The figure is not drawn to scale. What is the shaded area?
Penjelasan dengan langkah-langkah:
triangle 1
= 1/2 x a x t
= 1/2 x 10 x 12
= 60 cm2
triangle 2
= 1/2 x a x t
= 1/2 x 8 x 10
= 40 cm2
triangle 1 - triangle 2
= 60 cm2 - 40 cm2
= 20 cm2
