A playground has the shape of a rectangle, with two semi-circles on its smaller sides as diameters, added to its outside. If the sides of the rectangle are 36 m and 24.5 m, find the area of the playground. (Take π = 22/7.)

A playground has the shape of a rectangle, with two semi-circles on its smaller sides as diameters, added to its outside. If the sides of the rectangle are 36 m and 24.5 m, find the area of the playground. (Take &#x3C0; = 22/7.)

Philoid · Accepted Answer

Area of the plot = area of the rectangle + 2 × area of one semi-circle

Radius of semi-circle =

Area of the plot = length × breadth +

Area of the plot = 36 × 24.5 +

Area of the plot = 882 + 471.625 = 1353.625 m²
