OK so we have two formulas:
Length = width + 5 (since legth is 5 more than width)
length + width + length + width = perimeter= 82 (form. for perm.)
so we can replace every instance of "length" with "width + 5" since they are the same.
width + 5 + width + width + 5 + width = 82
4xwidth + 10 = 82
4X width = 72
width = 23
so now go back and replace "width" with 23.
length = 23 + 5
length = 28
There you go.
Perimeter = 2 x (length+width). You add the length to the width and multiply the sum by two.
The perimeter of a standard- sized rectangular rug is 94 ft. the length is 3 ft more than the width. Find the length and the width.
The width is 4ft the length is 16ft
divide perimeter by 6.
It isn't clear how you would define the "perimeter" for a 3D figure. The base is the product of length x width.
width*height*length=perimeter of a rectangular prism! :)

the length of a rectangular garden is 2 feet longer than 3 times it's width .if the perimeter of the garden is 100 feet find the width and length of the garden
divide perimeter by 6.

width = (perimeter-2*length)/2
the perimeter of a rectangular rug is 40 ft. the length is 2 ft longer than the width. find the dimensions
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
Length + length + width + width = perimeter. Length + width x 2 = perimeter
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
