Question

Find the cost of fencing a rectangular park of length 125 m and breadth 85 m at the rate of
15 per metre​

Answer 1

ANSWER

Fencing is done at the perimeter so, perimeter of rectangular park=2(l+b)=2(350+250)

⇒2×600=1200m

Rate of fencing per meter=Rs. 18.50

∴ Rate of fencing 1200 m =Rs.8.50×1200

=Rs.22,200

Answer 2

Length=125m

Breadth=85m

So,Perimeter=2(l+b)=2(125+85)=2 × 210=420m

Total Cost=420 × 15=6,300Rs/-
