How to solve a classmate draws a parallelogramfor whichone side is twice as long as the other. If one side is 26 units, what are all the possible lengths of the perimeter?

Answer: length when perimeter is 78 units: a=26, b=13

Length when perimeter is 156 units:

a=26, b=52

Step-by-step explanation: Given one side = 26, the other is twice as long

Perimeter of a parallelogram = 2 (a+b)

Using perimeter=78 = 2 (26+b)

78=52+2b

78-52=2b

26=2b

b=26/2

b=13

When perimeter is 78 units a=26, b=13

Using perimeter = 156 units

156=2 (26+b)

156=52+2b

156-52=2b

104=2b

b=104/2

b=52
