Question

How to find sides if area and permieter of a rectangle are given?

Answer 1

area = L × b
b= area ÷ length
perimeter = 2 (l + b)
perimeter = 2 ( l + (area ÷ length) )
perimeter = 2 (l^2 +area)÷l
perimeter ÷2 = (l^2 +area)÷l
(perimeter ÷2) - area = 1÷l (l^2)
from above equation l can calculated with l breadth can be calculated
