Question

The length and breadth of a rectangular field is in the ratio 3:4 its area is 6912 sq.cm. Find its dimensions

Answer 1

look at the photo for answer

Answer 2

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
