Question

The width of rectangle is four-
fifth its length. If the perimeter
of the rectangle is gone. Find the
length and breadth of the
reclangle​

Answer 1

Answer:

Width is 4/5 L

P = 90 = 2L + 2 (4/5 L)

90 = 2L + 8/5 L

720 = 10 L + 8 L

720 = 18 L

L= 720/18 = 40 m

W = 4/5 × 40 = 160/5 = 32 m
