This is a good question, and you need to know the quadratic formula
let A = area
b = width
h = height
P = perimeter
A = bh
b = A/h
P = 2b + 2h
P = 2A/h +2h = (2h^2 + 2A)/h
Ph = 2A + 2h^2
2h^2 - Ph + 2A = 0
use quadratic formula to solve:
h =( P +/- SQRT(P^2 -16A))/4
This gives both sides b and h using plus then minus the square root

Area 36 and perimeter 40 what are the sides?
To find the sides of a rectangle with an area of 36 and a perimeter of 40, we can use the formulas: area (A) = length (l) × width (w) and perimeter (P) = 2(l + w). From the area equation, we have ( l \times w = 36 ), and from the perimeter equation, ( l + w = 20 ). Solving these equations, we find the dimensions to be ( l = 18 ) and ( w = 2 ), or vice versa. Thus, the sides of the rectangle are 18 and 2.
What is the formula of rectangle?
The formula of the rectangle is multiplying the length and the width to get the area. You can add all the four sides so as to find the perimeter of the rectangle.
