Answer:
11 units
Explanation:
Diagonals in a rectangle are congruent.
WY and XZ are both diagonals of the rectangle WXYZ.
Therefore, their values are congruent or equal.
6x-7 = 3x+2
Subtract 3x from both sides and add 7 from the left side to isolate the x's equal to a constant.
You get 3x = 9
Divide both sides by 3 to isolate x by itself.
x = 3
Next, plug in the value of 3 for x in any of the equations and you will get 11 units.
Hope this helps!
