What will be the cost of building a fence around a square plot with area equal to 289 sq ft, if the price per foot of building the fence is Rs. 58?

A. Rs. 3154
B. Rs. 3748
C. Rs. 3847
D. Rs. 3944

Answer

Correct Answer: D. Rs. 3944


Solution

Let the side of the square plot be ‘a’ ft.
Given area of the plot (a x a) = 289 => a = 17
Length of the fence = Perimeter of the plot = 4a = 68 ft.
Cost of building the fence = 68 x 58 = Rs. 3944.
