Question

The breadth of a mectangle is 15 m less than ito
length. The perimeter of in uectangle is 450m. Find the
area of rectangle .​

Answer 1

Step-by-step explanation:

Given,

Perimeter of the rectangle = 450m

Let the length of the rectangle be x m

There, breadth of the rectangle = (x -15)m

We know, 2(l + b) is the formula for perimeter of a rectangle.

Therefore, 2(l + b) = 450

= 2(x + (x- 15) = 450

= 2(2x - 15) = 450

= 4x - 30 = 450

= 4x = 450 + 30 = 480

= x = 480/4 = 120

Length = x = 120m

Breadth = x - 15 = 120 - 15 = 105m

Therefore, area of the rectangle = l * b = 120 * 105 = 12600m² (Ans)

Here is your answer. Hope it helps!
