Question

Find the cost of building a boundary wall around a rectangular plot hundred M long and 40 m 75 cm wide at the rate of Rs 23per metre. A 2.5 M long stretch is left on one of the longer side for entrance

Answer 1

formula for perimeter of rectangle=2(l+b)

length=hundred m

breadth=40 m 75 cm=40.75m

perimeter= 2(100+40.75)= 2x140.75 m=281.5 m

area in which wall is to be constructed=281.5-2.5=279 m

cost of building per m= Rs.23

cost of building the boundary= 279x23=Rs.6417
