2
Given:
The cost of fencing of the square plot is 156.4 rupees at the rate of 2.3 rupees per meter.
Concept:
Perimeter of square = 4 × side
Area of square = (Side)2
Calculation:
Here, the perimeter of the square plot is
⇒ 156.4/2.3
⇒ 68 m
Now, The side of the square plot is
⇒ 68/4
⇒ 17 cm
The area of the square plot is
⇒ (17)2
⇒ 289 cm2
∴ The required area of the square plot is 289 cm2.
