Question

A playground has the shape of a rectangle with two semicircles 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 playground.

Answer 1

given                                                              

length=36m                                                        

breadth=24.5m

area of rectangle =lxb

36 x 24.5=982sq.metres

area of semicircle =pi x r^2/2

pi value=22/7

diameter =24.5 because given two semicircles at smaller side as diameters added to its outside

radius=diameter/2

r=24.5/2

r=12.25

((22/7 x 12.25 x 12.25)/2)x2 its multiplied by 2 because there are 2 semicircles

=471.6250+area of recangle

=471.6250+982

=1453.6250

thee area of playground=1453.6250

mark it as brainliest please!!!
