Question

The length and breath of a rectangular field is in the ratio 3:4. It’s area is 6912 sq.cm find its dimensions.

Answer 1

The ratio of length to breadth is 3:4

let the length be 3x

breadth be 4x

area = 4x x 3x

6912 = 12x^2

x^2 = 576

x=24

length= 72

breadth =96

actually length will be greater than breadth

so the ratio must be 4:3 then alter the above length and breadth values
