Do you agree with this?

solomonzelman · Answer

(Taking the difference of those triangles (lower left and the entire left) - to find the area of the upper left triangle.)

anonymous · Answer

yeah so i do same thing to other side just double the area

solomonzelman · Answer

We will see if the x will be a factor in your answer, then you understand that this left WILL impact the area.

solomonzelman · Answer

and if x goes away (cancels), then information is correct and we didn't need to know this length,.
