Question

Find the cost of levelling a playground at rs. 5 per square metre if it is 28m long and 16m wide. also, find the cost of fencing it at rs. 2.40 per metre.

Answer 1

since levelling is done on the entire ground so area to be levelled will be = to the Area of ground so .
a= l×b
=28*16
=448msq
cost = 5*448=2440₹
now fencing it will be equal to the boundary length so 2(16+28)
= 2*44 = 88m
cost of fencing = 88*2.40 = 211.2₹
hence solved

Answer 2

Step-by-step explanation:

since levelling is done on the entire ground so area to be levelled will be = to the Area of ground so .

a= l×b

=28*16

=448msq

cost = 5*448=2440₹

now fencing it will be equal to the boundary length so 2(16+28)

= 2*44 = 88m

cost of fencing = 88*2.40 = 211.2₹

hence solved
