Answer:
1) A = 112 cm²
2) A = 130.24 cm²
3) A = 96 cm²
Step-by-step explanation:
Rectangle Formula: Length x Width
Triangle Formula: Base x Height ÷ 2
Circle Formula: π r²
1) Rectangle Area:
A = 12 x 8
A = 96
Triange Area:
A = 8 x 4 ( ÷ 2 )
A = 32 ÷ 2
A = 16
96 + 16 = 112 cm²
2) Circle Area:
A = (3.14) 4 x 4
A = 3.14 x 16
A = 50.24
Rectangle Area:
A = 8 x 10
A = 80
50.24 + 80 = 130.24 cm²
3) Rectangle Area:
A = 8 x 10
A = 80
Triangle Area:
A = 8 x 4 (÷ 2)
A = 32 ÷ 2
A = 16
80 + 16 = 96 cm²
