The parallelogram is shown below I have an area of 135 units. Find the missing base

9

Step-by-step explanation:

The area of a parallelogram is base * height.

The area is given as 135

The height is given as 15

You do not need to use 17

Area = base * height       Substitute

135 = base * 15                Divide by 15 on both sides

135/15 = base*15/15

base = 9  

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
