Question

Find the area of the following shape (in sq. cm)

• A. 12
• B. 24
• C. 36
• D. 48

Answer 1

The correct option is D

48

Area of the above shapes can be calculated in two steps:

i) Area of shape marked 1

ii) Area of shape marked 2

Area of shape marked 1 = Area of rectangle = length x breadth

= 4 x 9

= 36 cm²

Area of shape marked 2 = Area of triangle = $\frac{1}{2}$ x base x height

= $\frac{1}{2}$ x 6 x 4

= 12 cm²

Area of shape = Area of shape marked 1 + Area of shape marked 2

= (36 + 12) cm²

= 48 cm²
