Question

The perimeter of a rectangle is 720 cm. Find its
length if its breadth is 150 cm.​

Answer 1

To Find:-

The length of the rectangle

Given:-

Perimeter of the rectangle = 720cm

Breadth of the rectangle = 150cm

Formulae Applied:-

Perimeter of a rectangle = 2 ( l + b)

l = length

b = breadth or width

Solution:-

Let the length be x

A.T.Q we have,

2( x + 150) = 720

x + 150 = 720/2

x + 150 = 360

x = 210

Therefore,

➝ Length of the rectangle is 210cm.

Important Formulae:-

☞Perimeter of the rectangle - 2 ( l + b)

☞Area of a rectangle - L × B
