Question

The cost of constructing a boundary wall around a rectangular plot is RS.20,480 at the rate of RS.40 per metre. Find the length if its breadth is 16 metre.​

Answer 1

Answer:

Length = 32 metres      

Explanation:

Cost of constructing a boundary wall around a rectangular plot = Rs.20,480

Cost per meter-Rs.40

Thus, The total area= 20,480/40 = 512 meters squared

Area of a rectangle =length x breadth

Length of a rectangle= area/breadth

(Breadth = 16 meters)

Thus, 512/16=32

Thus, the length of the rectangular plot is 32 meters
