Question

1. The ratio of the length and breadth of a rectangle is 5: 4. If the length is 25 m, the breadth is
(1) 15 m
(2) 20 m
(3) 10 m
(4) 12 m​

Answer 1

As we know that:-

• Ratio of length is to breadth is 5 : 4

• length/breadth = 5/4

Substituting Values:-

25/b = 5/4

5b = 25 × 4

5b = 100

b = 100/5

b = 20 m

Solution:

Ratio of the length and breadth of a rectangle is 5 : 4

Let, length = 5 m

Breadth = 4 m

According to problem,

⇒ 25/b = 5/4

⇒ 5b = 25×4

⇒ 5b = 100

⇒ b = 100/5

⇒ b = 20m

∴ Length of the rectangle = 20m
