Answer 2

Step-by-step explanation:

Hi,

Let sides of rectangle are 4x and 5x.

Length = 5x units and Breadth = 4x unit's

Given : Perimeter of rectangle is 20 unit's.

Also,

Perimeter of rectangle = 2 ( L + B )

20 = 2 ( L + B )

20 = 2 ( 5x + 4x )

20 = 2 × 9X

20 = 18x

X = 20/18

X = 10/9

Therefore,

Length = 5x= 5 × 10/9 = 50/9 unit's.

And,

Breadth = 4x = 4 × 10/9 = 40/9 unit's.
