ok... this is what you know when you draw the picture


|dw:1366674094375:dw|

so then the area of a parallelogram is A = base x height

$$972 = b \times 3b$$

or 

$$972 = 3b^2$$

just solve for b

972=3b^2
/3       /3
324=b^2
18=b

that seems to be correct.. so the base is 18 and height = 3x18
