The length of a rectangular plot is 20 m more than its breadth. The cost of fencing the plot is Rs. 2200 at the rate of Rs. 5 per meter. What is the length of the plot? Correct Answer 120 <span style="">m</span>

Given:

The cost of fencing of the plot = 2200

Formula used:

The perimeter of the rectangle = 2 × (a + b)     Where a = The length of the rectangle, and b = The breadth of the rectangle

Calculation:

Let us assume the breadth of the rectangle be X

⇒ The length of the rectangle = X + 20

⇒ The perimeter of the rectangle = 2200/5 = 440 m

⇒ 440 = 2 × (X + X + 20)

⇒ 440 = 4X + 40

⇒ 440 - 40 = 4X

⇒ X = 100 m

⇒ The length of the rectangle = X + 20 = 100 + 20 = 120 m

∴ The required result will be 120 m.
