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


Correct Answer: D. Rs. 3944


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.
