Question

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

Answer 1

Let the length be 3x and breadth be 4x. We know that, Area of rectangle= l×b. Therefore, 3x×4x=6912 m^2

implies 7x^2 = 6912 m^2

implies x^2 = 6912/7 m^2 =987.41m^2

implies x=√987.41 m

Therefore, length = 3√987.41 and breadth= 4√987.41

Hope it helps!!
