364 cm²
Step-by-step 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
