Question

(Hint: Area = area of a rectangle + area of a circle)​

Answer 1

Required area = 2×1.4 + 22/7×0.7×0.7

= 4.34m square

Answer 2

4.34 m²

Step-by-step explanation:

Given:

Diameter = 1.4m

Radius = 1.4 / 2 = 0.7m

Length of rectangle = 2m

Width of rectangle = 1.4m

Computation:

Area of rectangle = Length x Width

= 2m x 1.4m = 2.8 m²

area of 2 semi circle = 2 x 1/2$\pi r^2$

= $\pi r^2$

= 22/7 x 0.7 x 0.7

= 1.54 m²

Area of given figure = Area of rectangle + area of 2 semi circle

= 2.8 m² + 1.54 m²

= 4.34 m²
