Question

A path 2.8m wide rung along inside a square park off side 98 m . find the cost of levelling the path at the rate of 2.25 per m

Answer 1

area of the square park = side X side

=98 x 98

=9657 square m

area of the park excluding the path

=side x side

=(98-2.8-2.8) x (98-2.8-2.8)

=92.4 x 92.4=8537.76 square m

now , the are of the whole park - the area of the park excluding the path = area of the path=9657 - 8537.76=1119.24 square m

rate of levelling = 2.25 per m

cost of levelling = 2.25 x 1119.24

=Rs 2518.29

Hope this will help you
