∙ 12y agoto get the perimeter you take 12 x 2 and 22 x 2 get those numbers then add them and you have your perimeter

∙ 12y agowidth*height*length=perimeter of a rectangular prism! :)
Add up all of the lengths of the edges adjacent to one of the bases.
divide perimeter by 6.
12 the base times the height
12 the base times the height
The perimeter of a rectangle (proper name of the shape) is just the length of all the sides added together.
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.
The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
To find the perimeter of a triangle, add the three sides. Perimeter = 6in + 8in + 10in = 24in.
you just take the length of it's midsegment and multiply it by its height to find area. to find it's perimeter, just add the measures of it's sides
