Question

length of rectangular park is 780m and its breadth is 320m. what would it cost to fence the park at the rate of rs. 7.50 per meter?

Answer 1

Answer:

length =780 m

breadth = 320 m

fence word is used when we need to calculate the perimeter

so,perimeter is=

2(l+b)

2(780+320)

2*1100

2200 m

therefore,cost to fence the park at rs. 7.50 per m is=

2200*7.50

=rs. 16,500

Answer 2

Answer:

area of rectangular park = 780×320 m

=249600

cost of fencing 1 m =7.50

thus 249600=249600÷7.50

33280
