Greg drew a square with each side equal to z units. Part A: Greg increased the length and width of the square by t units each. What will be the change in the area of the original figure? Show your work.

OpenStudy (anonymous):

I got as far as 4z + 4. Sorry, but I don't quite know how to do it from there.

undeadknight26 (undeadknight26):

thanks man :)

OpenStudy (solomonzelman):

you know that the area of the square is side squared. So, if you add t to each side, it would be (z+t)^2 Correct?

undeadknight26 (undeadknight26):

Correct...but they never told me the original side of it.

OpenStudy (solomonzelman):

it is equal to Z
