Expert Answer:

Radius of semicircular ends = d/2 = 7/2 = 3.5 m
Length of rectangle = 20 - (3.5 + 3.5) = 13 m
Breadth of rectangle = 7 m
Area of garden = area of rectangle + area of two semicircles
                       = lb + 2 × ∏r2/2
                       = 13 × 7 + 22/7 × 3.52 
                       = 129.5 m2
