Answer 1

length of the rectangle = 20 - (3.5 + 3.5)

length of the rectangle = 20 - 7

length of the rectangle = 14 cm

breadth of the rectangle = 7 cm

diameter of the semi-circle = 7 cm

∴ radius of the semi-circle = 7/2 cm

ar. of the garden = ar. of the rectangle + ar. of 2 semi-circles

ar. of the garden = length × breadth + 2 × 1/2 × πr²

ar. of the garden = 14 × 7 + 2 × 1/2 × 22/7 × 7/2 × 7/2

ar. of the garden = 98 + 77/2

ar. of the garden = 136.5 cm²
