Question

The ratio of the length to the breadth of a rectangular field is 5 : 4. If length of the field is 35 m,
find the breadth of the field.​

Answer 1

Answer:

Step-by-step explanation:

The ratio between the length and breadth of a rectangular field is 5 : 4 if the breadth is 20m less than the length, the perimeter of the field is :

A) 260m

B) 280m

C) 360m

D) none of these

=> Option C

Explanation:

Let length of rectangular field = 5y,

so width = 4y.

From question

5y - 4y = 20m

⇒ x = 20m  

∴ Length = (5 x 20)m = 100 m

Breadth = (4 x 20) m = 80 m  

∴ Perimeter = 2 (100 + 80 ) m = 360 m
