Calculate the shaded area of the figure
1. Calculate the shaded area of the figure
Ibaratkan :
segitiga besar = a
segitiga kecil = b
Diketahui :
panjang alas a = 62 cm
panjang alas b = 62 cm
tinggi a = 30 cm
tinggi b = 21 cm
Jawab :
Luas arsiran = (luas a)-(luas b)
L = (62 x 30/2) - (62 x 21/2)
L = (1860/2) - (1302/2)
L = 930 - 651
L = 279 cm^2
Maaf jika ad kesalahan :)

8. 3. Find the shaded area. 3oft. 2524
Jawaban:
375 ft²
Penjelasan dengan langkah-langkah:
d1= 30 ft
d2= 25 ft
a= 30 ft
t= 25 ft
Luas= a × t - 1/2 × d1 × d2
= 30 ft × 25 ft - 1/2 × 30 ft × 25 ft
= 750 ft² - 15 ft × 25 ft
= 750 ft² - 375 ft²
= 375 ft²
9. find the area of the shaded parttolong dengan cara
Cara:
Dicari dulu luas kedua segitiga.
[tex]l = \frac{axt}{2} [/tex]
L = Luas a = alas t = tinggi
[tex]l 1 = \frac{12x12}{2} = 72cm {}^{2} [/tex]
[tex]l2 = \frac{12 \times 5}{2} = 30cm {}^{2} [/tex]
angka 5 dari mana? dari 12 - 7 = 5 cm, yang merupakan tinggi segitiga kecil.
[tex]ls = 72 - 30 = 42cm {}^{2} [/tex]
10. The figure is not drawn to scale. Find the area of the shaded triangle.
Jawaban:
484
Penjelasan dengan langkah-langkah:
Area of triangle = Base x Height
= 22 x 22
= 484
So, the area of the shaded triangle is 484
11. Find the area of the shaded part!
[tex]luas \: segitiga = \frac{alas \times tinggi}{2}[/tex]
[tex]luas \: persegi = panjang \: \times \: lebar[/tex]
Jumlah bangun,
2 Segitiga (Alas dan Tinggi = 6 cm)
1 Persegi Panjang (Panjang = 20 cm dan Lebar = 6 cm)
Maka,
[tex]2 \times luas \: segitiga + luas \: persegi[/tex]
[tex] = 2 \times \frac{6 \times 6}{2} + 20 \times 6[/tex]
[tex] = 36 + 120[/tex]
[tex]luas = 156 \: {cm}^{2} [/tex]
Tolong jadikan jawaban terbaik ya! :)
12. find the area of shaded region
Jawaban:
The example is wrong, It doesn't make sense
1. 9750 cm2
2.
Penjelasan dengan langkah-langkah:
1.
[tex] \frac{3}{4} \times ( \frac{22}{7} \times {35}^{2} ) \\ \frac{3}{4} \times ( \frac{22}{7} \times 3850 ) \\ \frac{3}{4} \times 12100 \\ = 9750 cm {}^{2} [/tex]
2.
[tex] = 3.14 \times {12}^{2} \\ = 3.14 \times 144 \\ 452.16cm {}^{2} [/tex]
[tex] = \frac{22}{7} \times {7}^{2} \\ = \frac{22}{7} \times 49 \\ = 154cm {}^{2} [/tex]
[tex]452.16 - 164 = 288.16cm {}^{2} [/tex]
Sorry if I'm wrong
13. Find the area of the shaded region.
Sector area AOB :
θ/360° × πr²
= 58°/360° × π(5)²
= 29°/180° × 25π
= 145π/36
= 12.65 cm²
Missing side (AT) of triangle TAO:
tan(58°) = AT/5
AT = 5tan(58°)
AT= 8 cm
Area of triangle TAO:
1/2 × base × height
= 1/2 × AO × AT
= 1/2 × 5 × 8
= 20 cm²
Shaded region:
TAO - AOB
= 20 cm² - 12.65 cm²
= 7.35 cm²
14. Find the area of each shaded triangle
Jawaban:
e. The area of triangle is 140 m
f. The area of triangle is 100 m
g. The area of triangle is 72 m
h. The area of triangle is 225 m
Penjelasan dengan langkah-langkah:
The pattern of triangle area is
A = ½ × b × hb = base
h = height
Let's answer each question (Q)
Q.e
b = 8 m
h = 35 m
A = ½ × b × h
A = ½ × 8 × 35
A = ½ × 280
A = 140
Q.f
b = 20 m
h = 10 m
A = ½ × b × h
A = ½ × 20 × 10
A = ½ × 200
A = 100
Q.g
b = 12 m
h = 12 m
A = ½ × b × h
A = ½ × 12 × 12
A = ½ × 144
A = 72
Q.h
b = 30 m
h = 15 m
A = ½ × b × h
A = ½ × 30 × 15
A = ½ × 450
A = 225
15. Find the area of the shaded part
Jawaban:
32cm²

19. Find the area of the shaded part.
We have width 8 cm. Each of the width that has been bisect is 4 cm. Now, we need to find the smallest white triangle (with the base 4 cm) and a triangle with the base 8 cm.
[tex] \displaystyle \underset{\text{White}}{\text{Area}} = \frac{1}{2} \times 4 \times 14 = 28 [/tex]
[tex] \displaystyle \underset{\text{White}}{\text{Area}} = \frac{1}{2} \times 8 \times 14 = 56 [/tex]
Now, to find the shaded area part, we just have to subtract all of them.
[tex] \displaystyle \underset{\text{shaded part}}{\text{Area}} = 56 - 28 = 28 [/tex]
20. find the area of each shaded triangle
