# QName the lenghts of the sides of three rectangles with a perimeter of 12 units use whole numbers only

Name the lenghts of the sides of three rectangles with a perimeter of 12 units use whole numbers only. I don't understand the question

This question still have no answer summary yet.
how do you find the perimeter

The questions is telling you that there are three possible rectangles whose perimeter is 12 units and whose sides are whole numbers in length.

The perimeter of a rectangle is given by 2(L+B).

So, this means that L+B = 6.

What whole numbers add up to 6?

1+5 = 6
2+4 = 6
3+3 = 6

And those are your rectangles. One has sides of 1 and 5 units, the second has 4 and 2 unit sides and the third is a square with a 3 unit side.
using only whole numbers, how to can i draw 3 rectangles with perimeter of 12 units
name the lenghts of the sides of three rectangles that have perimeters of 14 units
Each rectangle has a perimeter of 12 units.

P = 2L + 2W

12 = (2 * 4) + (2 * 2)

12 = (2 * 3) + (2 * 3)

Can you think of the possible dimensions of a third rectangle?
