Question

What is the area of this? Please help

Answer 1

364 cm²

Explanation:

Area of the figure :

• Area (triangle) + Area (rectangle 1) + Area (rectangle 2) + Area (rectangle 3)
• 1/2 x 20 x 14 + 12 x 9 + 7 x 3 + 19 x 5
• 140 + 108 + 21 + 95
• 248 + 21 + 95
• 269 + 95
• 364 cm²

Answer 2

364 cm²

Explanation:

Area of Triangle = 1/2 × B × H

• where B is a base and H is height , given in the figure.

=> 1/2 × 20 × 14

=> 140 cm²

Area of Rectangle A = L × B

• where L is Length and B is base of the rectangle.

=> 12 × 9

=> 108 cm²

Area of Rectangle B = L × B

• To find the length and breadth we have to subtract ;

=> 12 - 5 = 7 -------- Length

=> 8 - 5 = 3 -------- Breadth

=> 7 × 3

=> 21

Area of Rectangle C - L × B

=> 19 × 5

= 95 cm²

Total area = Area of Triangle + Area of Rectangle A + Area of Rectangle B + Area of Rectangle C

=> ( 140 + 108 + 21 + 95 ) cm²

=> 364 cm²
