Answer 2

Answer:

Length of rectangle is 40 cm. and breadth is 20 cm.

Step-by-step explanation:

Given:

Perimeter of rectangle = 120 cm.

Let breadth of rectangle = x cm.

Length of rectangle = x+ 20 cm.

As we know that,

Perimeter of rectangle = 2( length +breadth)

                120 = 2 {( x+20 ) +x}

                120 / 2 = x+20 +x

                   60 = 2x +20

                  60 - 20 =2x

                      40 /2 =x

                    20 =x

Breadth of rectangle = 20 cm.

Length of rectangle = 20 + 20 =40 cm.
