Question

please answer with full steps

Answer 1

No of stone slabs = 50
Because equal size so it is a square.
Total area to be covered = 72sq. m
therefore,
area of square = s^2
$72 = ( {s}^{2} )50 \\ \frac{72}{50} = {s}^{2} \\ \frac{36}{25} = {s}^{2} \\ \sqrt{ \frac{36}{25} } = s \\ \frac{6}{5} = s \\ s = 1.2$
So, Now this is 1.2m
Let convert it into cm = 1.2×100 =120cm
So answer is 120cm
