Question

the side of a square plot is 200m. A road of uniform width of 4m is constructed along its boundary outside the plot. Find the cost of constructing at the cost of rupees 15 per square meter

Answer 1

Step-by-step explanation:

Area of a square plot= (side)^2 = (200)^2 = 40,000 m^2.

A 4m road along it's boundary is constructed outside the plot.

So, the are of the other square plot =

(side)^2 = (200+4+4)^2 = (208)^2 = 43264 m^2.

Area of the road = 43,264 - 40,000 = 3,264 m^2.

The total cost for constructing the road = 3,264 × 15 = 48,960 rupees

Answer 2

Answer:

Area = 40,000m^2

Cost = 48,960 rs

Step-by-step explanation:

Area of a square plot= (side)^2 = (200)^2 = 40,000 m^2.

A 4m road along it's boundary is constructed outside the plot.

So, the are of the other square plot =

(side)^2 = (200+4+4)^2 = (208)^2 = 43264

m^2.

Area of the road = 43,264 - 40,000 = 3,264 m^2.

The total cost for constructing the road = 3,264 x 15 = 48,960 rupees...
