Greg drew 3 squares with each side equal to z units. For each square, he does something different to it according to each part below:

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.

Part B: Greg decreased the length and width of the square by t units each. What will be the change in the area of the square? Show your work.

Part C: Greg increased the length of the square by t units and decreased its width by t units. What will be the change in the area of the square?

with z units, the area of square = z^2 
this is similar to s^2 the s was just changed to z

a)  greg increased the length and with (which is for both) by t units 

new area will be (z+t)^2 

b) decrease by t units 

new area will be (z-t)^2

c) increase the length by t units and decrease the width by t units 

length now will be z+t 
width now will be z-t

and since area of the square is z^2, it must mean that the length and width have the same size, but in the case C, it is bigger by t and smaller by t  if you realize, this will now be area of a rectangle 

area of a rectangle = length * width 
and since our length is z+t and our width is z-t
area = (z+t) * (z-t)
