Question

the sides of a rectangle are in ratio 4 5 and its perimeter is 108 cm, then find the length and breadth of the rectangle

Answer 1

Answer:

length=48cm breadth=60cm

Step-by-step explanation:

length ratio =4x

breadth ratio =5x

total =108cm

4x+5x=108 cm

9x=108cm

x=108/9

x=12 cm

Answer 2

Step-by-step explanation:

The sides of a rectangle are in the ratio of 4:5. If the perimeter of the rectangle is 90 cm. find its sides.

Sides of the rectangle are in the ratio of 4:5

Let the length l=5x

and the breadth b=4x

Now, perimeter =2(l+b)=90cm

2(5x+4x)=90

2(9x)=90

18x=90

x=5

Therefore, Length l=5x=25cm

and the breadth b=4x=20cm
