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
Part B: the same thing as a but you are decreasing by t and show your work
Part C: increased the length by t and decreased the width be t

Answer 1

wat is T?

Answer 2

First the square is \(z\) by \(z\). Area of a square = \(s^2\) where \(s\) is the side length, so the area of the initial square is \(A=z^2\).

If he increases the sides to \(s=z+t\) the area changes to \(A=(z+t)^2 = z^2+2zt + t^2\) Subtract the area of the original square to find the increase.

That should give you enough to go on.

Answer 3

Area of the figure in part C will be \[A = l*w\]where \(l\) is the length and \(w\) the width

Answer 4

thx @whpalmer4

Answer 5

T is a variable representing what he added or subtracted from the length and width @theonlycool13

Answer 6

You're welcome!

Answer 7

Oh ok
