Solution:-)

Here, length of rectangle = 20 – (3.5 + 3.5) = 13 m, breadth = diameter of semi circle = 7 m

Diameter of Semi Circle = 7 m, i.e. radius r = 7/2 m = 3.5 m

Area of the garden = sum of areas two semicircular shapes + area of rectangle

Area of the garden = π r2 + Length × Breadth.

area \: of \: garden =  \frac{22}{7}  \times 3.5 \times 3.5 + 13 \times 7 \\  = 22 \times 0.5 \times 3.5 + 13 \times 7 \\  = 38.5 + 91 \\  = 129.5cm {}^{2}

And perimeter = Total Length of Outer

Boundary

= Circumference of Circle + 2 × Length of rectangle

Perimeter of the garden = 2 π r + 2 l

perimeter \: of \: garden =  \: 2 \times  \frac{22}{7}  \times 3.5 + 2 \times 13 \\  = 22 + 26 \\  = 48m

Hope it helps you ❣️☑️
