Answer 2

☆ Solution ☆

Given :-

• Perimeter of the rectangle = 56

• Breadth of the rectangle is = 20

To Find :-

• The length of the rectangle .

Step-by-Step-Explanation :-

Let,

• The length of the rectangle be l

As we know that :-

Perimeter of the rectangle = 2 ( l + b )

Where,

• Perimeter of the rectangle = 56

• l = l

• b = 20

Putting the respective value,

56 = 2 ( l + 20 )

56 = 2l + 40

2l = 56 - 40

2l = 16

l = 16/2

l = 8

Hence,

The length of the rectangle is 8 units
