You need to solve the two equations
P = perimeter
A = area
B = width
H = height
P = 2B + 2H
A = BH
H = A/B
P = 2B + 2A/B
P = (2B^2 + 2A)/B
2B^2 -PB +2A = 0
B = (P +/- SQRT(P^2-16A))/4
ONE ROOT IS B, the other is H

How do you find the optimal area of a rectangle given its perimeter?
Multiply length by width
What is the area of a rectangle that its perimeter is 39?
156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.
What measurements do you need to find the area and perimeter of a rectangle how would you use these measurements to find the area and perimeter of a rectangle?
you need length and width length multiply width = area length + length + width + width = perimeter
What is the difference between perimeter and area of polygon?
perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or rectangle)
How do you find the length and width of a rectangle when given the area and perimeter?
By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.
How do you find the optimal area of a rectangle given its perimeter?
Multiply length by width
The length of a rectangle is twice its width If the perimeter of the rectangle is 54y find its area?
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
The length of a rectangle is 5 more then the width Find the perimeter and the area of the rectangle?
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle

156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.
What measurements do you need to find the area and perimeter of a rectangle how would you use these measurements to find the area and perimeter of a rectangle?
you need length and width length multiply width = area length + length + width + width = perimeter
How is perimeter and area related in a rectangle?
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
What is the difference between perimeter and area of polygon?
perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or rectangle)
How do you find the length and width of a rectangle when given the area and perimeter?
By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.
How do you find the perimeter of a rectangle with only the width or length and the area given?
It not possible you nit witt that is not true length x width = area If you know length and area, solve width width = area / length then 2 x length + 2 x width = perimeter
A rectangle has a length of 5.50 and a width of 12.0 What are the perimeter and area of a rectangle?
perimeter, area =35.0,66.0 , Travis Garner Rocks!
How do you find the dimensions of a rectangle given only the total perimeter?
Length + width = half the perimeter, but more info eg area, is needed.
A rectangle has a length of six cm What is its width if its perimeter and area are the same number?
18cm is the area and perimeter. the width is 3cm.
