a spuare park which has a side of length 40m has a concentric square with side of 35m inside it. Find the cost of cementing is 50 rupees per sq. m

$\sf \bf \huge {\boxed {\mathbb {ANSWER}}}$

$= Rs. 18750$

$\sf \bf {\boxed {\mathbb {SOLUTION}}}$

area required for cementing = ar(lareger square) - ar(smaller square)

$= (40)^2 - (35)^2$

$= 1600-1225$

$= 375 sq.m$

$cost = 375 × 50$

$= Rs. 18750$
