Question

The length and breadth of a rectangular field are in the ratio 7:5. If its perimeter is 480 m, find its dimensions.

Answer 1

Answer:

Let the length be 7x and breadth be 5x

Step-by-step explanation:

Perimeter = 2 x ( length + breadth )

So given perimeter = 480

Equating the 2 equations -

2 x ( 7x + 5x ) = 480

12x = 480/2

12x = 240

x = 240/12

x = 20.

So the length is = 20 x 7 = 140.

And breadth = 20 x 5 = 100
