Question

The sides of a rectange are in the ratio 4 : 5 and its perimeter is 180 cm. Find its sides​

Answer 1

Step-by-step explanation:

given that

perimeter = 180 cm

ratio = 4 + 5 = 9

4/9*180=80

5/9*180=100

Answer 2

Answer:

l=25cm

b=20cm

Step-by-step explanation:

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
