answer this question
Answers
Step-by-step explanation:
let the rectangular path be abcd and path be pqrs
Area of rectangular abcd park = l*b
=80×52
=4160m square
Pq =80-5-5=70
qr =52-5-5=42
area of rectangular pqrs = l*b
=70×42
=2940m square
area of path=area of rectangle abcd- area of rectangle pqrs
=4160- 2940
=1220m square
cost of cementing 1m square = ₹8.25
cost of cementing 1220m square = 8.25×1220
=₹10065
hence,cost of cementing 1120m square path is ₹10065.
