Question

the ratio of the length of a rectangular file its width is 4:3 the perimeter of the field is 308meters what are its dimensions? p=2l+2w

Answer 1

Let length and breadth are 4x & 3x respectively.

\(\therefore\) Perimeter = 2(4x + 3x) = 14x

\(\therefore\) 14x = 308 m

⇒ \(x = \frac{308}{14}\,m = 22\,m\)

\(\therefore\) l = 88 m

b = 66 m
