A rectangle has a perimeter of 26, and one of its sides has a length of 5 cm. sketch the rectangle and label all of its side lengths

If all the sides add up to 26 and one side has the length of 5, then you should know that there are 2 sides have the same length so what you have to do is draw a rectangle. you have two sides that are shorter than the other two sides. If you mark one side 5 cm (its best to use the shorter side for this problem - you will see why later) the one across from it should be 5 also. So then you subtract a total of ten from 26. 5+5=10 both sides equal 10, but the perimeter is 26 in total so you then subtract. 26-10=16. 16 is the total of both of the other sides put together so divide 16 by 2, 16/2 = 8---> label the short sides 5 and the longer sides 8.
