Answer 1

Correct Answer - Option 4 : 125 m

Given:

The area of rectangle = 12500 m²

The length is 25% more than breadth

Formula Used:

The area of rectangle = length × breadth

Calculation:

Let the breadth of the rectangle be x

⇒ length = (x) × (125/100)

⇒ 1.25x

According to the question, we have

(1.25x) × (x) = 12500

⇒ x² = 10000

⇒ x = 100

Now,

The length of rectangle = 1.25 × 100

⇒ 125 m

∴ The length of the rectangle is 125 cm.
