Question

The breadth of a rectangular garden is 4 m less than its length. If the length of the garden is 25 m, find the perimeter of the garden ?​

Answer 1

Answer

Length is 20 m and Breadth is 16 m

Let the width of the garden =x meter

Then length=(x+4) meter

Half perimeter =36 m

So perimeter of garden =(2×36)=72 meters

According to the question

⇒2(l+b)=72

⇒2(x+x+4)=72

⇒2x+2x+4=74⇒4x=64⇒x=16 meters

Hence,the width of the garden =16 meters

The length of the garden =(16+4)=20 meters
