The perimeter of a rectangle (proper name of the shape) is just the length of all the sides added together.
width*height*length=perimeter of a rectangular prism! :)
Add up all of the lengths of the edges adjacent to one of the bases.
It depends on a rectangular what.
divide perimeter by 6.
12 the base times the height
12 the base times the height
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
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). You add the length to the width and multiply the sum by two.
to get the perimeter you take 12 x 2 and 22 x 2 get those numbers then add them and you have your perimeter
Perimeter=24ft
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.
