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?

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

answer: 88

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
