Find the height h of the parallelogram.

Hey there :)

We know that the area of a parallelogram 
Area = base × height

We are given:
Base = 18 units
Height = 10 units

Apply the formula
A = 18 × 10 
   = 180 units²

and then
Area = 12 × h
180 = 12h

Divide by 12 on either side to isolate h and find its value

h = 15 units
