Step-by-step explanation:
area of the garden
= area of both the semicircle + area of the rectangle
area of the semicircle
= 1/2 × πr²
= 1/2 × 22/7 × (7m)². [r = 14m/2 = 7m]
= 1/2 × 22/7 × 7m×7m
= 1/2 × 154m²
= 77m²
area of both the semi circles
= 2×77m²
= 154m²
area of the rectangle
= length × breadth. [length = 40m - 7m -7m]
= 26m × 14m
= 364m²
area of the garden = 154m² + 364m²
= 518m²
perimeter of the garden
= 2×(πr) + 26m + 26m
= 2×(22/7 × 7m) + 52m
= 44m + 52m
= 96m
