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.
width*height*length=perimeter of a rectangular prism! :)
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.
Perimeter = 2 x (length+width). You add the length to the width and multiply the sum by two.
The width is 4ft the length is 16ft
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
It isn't clear how you would define the "perimeter" for a 3D figure. The base is the product of length x width.
the perimeter of a rectangular rug is 40 ft. the length is 2 ft longer than the width. find the dimensions
divide perimeter by 6.
width = (perimeter-2*length)/2
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
Length + length + width + width = perimeter. Length + width x 2 = perimeter
The perimeter is the total distance around - width + width+ length + length.
Length is 3/4 of 36 ie 27 ft, width is 9 ft
you need length and width length multiply width = area length + length + width + width = perimeter
just find the perimeter
If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.
Assuming the object is a rectangular parallelepiped, use its density to find its volume and solve the equation V abc for c where a, b, and c are the height, length and width respectively
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 + width = half of perimeter, so you need more information...
Length = (Perimeter - twice width) / 2
You divide the perimeter by the width and you get the lenght
The formula for perimeter is 2l+2w or 2*length + 2*width. This means that you multiply the length by two and multiply the width by two. Then, you add the two products together to find the perimeter.
Perimeter = Width x 2 + length x 2. To find width, you minus the length from perimeter because opposite of ADD is SUBTRACT.
Length + width = ½ perimeter, ie 42 yards or 126 feet. L = 6 W so w = 126/7 = 18 feet and length is 108 feet ie 36 yards.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
