Find the value of x, y, and z. The trapezoids are similar.
The bottom was at first 22 and is now 14 that is a 700/11 % decrease
so we now decrease every side by 700/11%
I think you can do the rest.
Every side is decreased by 400/11%
14 / 22 = 0.636363 or 7/11
x = 15 * 7/11 = 9 6/11
y = 18 * 7/11 = 11 5/11
z = 14 * 7/11 = 8 10/11
