If the ratio of length and breadth of a rectangle is 5:4 and its perimeter is 180 m, then find length and breadth of the rectangle.
length = 50 meters and breadth = 40 meters
Given, the ratio of length and breadth of a rectangle is 5:4 and perimeter = 180 m.
∴ Let the length is 5x meters and breadth be 4x meters.
∵ Perimeter of a rectangle = 2×(length + breadth)
∴ 2×(5x+4x) = 180 m
⇒ 18x = 180
⇒ x = 10
∴ length = 5x
= 50 meters
and breadth = 4x
= 40 meters
