Question

A swimming pool 25 m by 10m has a concrete border all round. Find the area of the concrete border if it is 2.5 m wide at the sides and 5m at the ends

Answer 1

Hey!!

here is your answer >>>

The area of the total rectnagle would be

( 25 + 5 + 5 ) ( 10 + 2.5 + 2.5 )

(35)(15)

525

Area of the pool =

(25)(10)

250.

Area of the concrete wall,

(Area of total Rectnagle.)-( Area of swimmingP)

(525)-(250)

275 is the area of the concrete wall!.

Hope my answer helps!
