Question

the cost of levelling a square lawn at rupee 15 per square metre is rupees 19935 find the cost of fencing the lawn at rupees 22 per metre

Answer 1

Given

Cost of levelling =19935

Rate of levelling=₹15/m²

The area = cost of levelling / rate of levelling

=19935/15

=1329m²

The lawn is in square form then area= side ²

Side²=1329

$side = \sqrt{1329}$

Side of lawn =36.46 m

Perimeter of square lawn = 4x side

=4x36.45

=145.82m

Cost of fencing 1 m =22

Cost of fencing 145.82m =145.82x22

=₹3208.81
