Question

A PLAYground measure 300m by 170 m find the cost of planting grads on this at the rate of 80 per hundred meters​

Answer 1

Area=300*170

=51000m square

1 hectare =10000m square

=51000m square =5.1 hectare

5.1*80=408

Answer 2

Total area = 300 x 170 = 51000 $m^{2}$

Given, cost is 800 per $m^{2}$.

So, total cost = $\frac{51000}{800}= \frac{510}{8} =63.75$ $Rs$
