Answer 2

Answer:

Length = 25cm, Breadth = 20cm

Step-by-step explanation:

Let the length and breadth be 5x and 4x

Perimeter of a rectangle = 2 × (length + breadth) = 90 cm

According to the problem,

     2(5x + 4x) = 90

or,  18x = 90

or,      x = 90/18 = 5

Therefore, 5x = 5 × 5 = 25cm    and,

                  4x = 4 × 5 = 20 cm
