Q2 of 68 Page 15

A play ground 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 36m and 24.5m, find the area of the play ground..

Given:


AB = 36m


BC = 24.5m


Area of rectangular portion = 36×24.5 = 882m2


Radius of semicircular portion =


Area of both semicircular portion =


= 471.625


Area of play ground = 882+471.625 = 1353.62
