Answer» Correct Answer - Option 3 : 289 cm² 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.

Answer» Correct Answer - Option 3 : 289 cm²

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.
