Exponent notation is 10^2 square feet, and in words it is one hundred square feet.
Let RS be denoted as y.
Given that T is the midpoint of RS, this results in RT = TS = 
And W acting as the midpoint of RT, leads to
thus RW = WT = 
Given that Z is the midpoint of WS.
Meaning WZ = ZS = 
Consequently, TZ = TS - ZS = 
However, TZ is defined as x.
Thus, 
y = 8x = RS.
A) Length of RW = 
B) Length of WZ = 
C) Length of RS = y = 8x
D) Length of ZS = WZ = 3x.
An image is provided for clarification.
For a rectangle, the perimeter can be calculated as P=2l+2w. Assuming the length is horizontal and the width is vertical, the span between the x coordinates will give the length, while the span between the y coordinates will determine the width. Once these measurements are obtained, you can apply them to the perimeter formula. |7 -(-7)| = 14 gives l = 14, |5-(-2)| = 7 gives w=7. Therefore, P=2(14)+2(7), which results in P= 28+14, thus, P= 42.
