1.	Find the cost of levelling a playground at Rs. 5 per square metre if it is 28 m long and 16 m wide.
Answer» SINCE levelling is done on the entire ground so area to be levelled will be = to the Area of ground so . a= l×b =2816 =448msq cost = 5448=2440₹ now fencing it will be equal to the boundary LENGTH so 2(16+28) = 244 = 88m cost of fencing = 882.40 = 211.2₹ hence solved

Find the cost of levelling a playground at Rs. 5 per square metre if it is 28 m long and 16 m wide.

Answer»

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
