Question

Find the cost of fencing a rectangular park of length 175 m and breadth 125 m at the rate of Rs 12 per metre.Sweety runs around a square park of side 75m . bulbul runs around a rectangular park of length 60m and breadth 45m . who covers less distance ?

Answer 1

Q1)cost of fencing=price*perimeter of park
=12*2(175+125)
=24(300)
=7200
Q2) perimeter of square park = 4l =4*75=300 m
perimeter of rectangular field =2(l+b)=2(60+45)=2(105)=210 m
difference between them=300-210=90m
bulbul runs less distance by 90 m.
