∙ 8y agoThe perimeter of a rectangle = 2 (w + h) where w is the width and h is the height.Accordingly, perimeter = 2 ( 2y + 3 + y - 7) = 2 (3y - 4) = 6y - 8

You divide the perimeter by the width and you get the lenght
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 do you find the perimeter of a rectangle when given the base and height?
all you have to do is add together the four sides. 2L+2W=Perimeter (L=length or base, W=Width or height)
How do you solve - A rectangle has a width of 2y plus 3 and height of y-7. Find the perimeter of the rectangle?
Add together the lengths of each of its sides.
What is one different way to to find the perimeter of a rectangle?
Length + length + width + width = perimeter. Length + width x 2 = perimeter

Length + length + width + width = perimeter. Length + width x 2 = perimeter
How do you find the length of a rectangle if the perimeter is 40 and the width is 2inches?
perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in
How do you find the height of a rectangle with the base and perimeter given?
Height = (Perimeter/2) - Base
How do you find the width of a rectangle if you know the perimeter and the length?
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
What is the formula to find the length of a rectangle when the perimeter and width is already given?
Length = (Perimeter - twice width) / 2
