U can refer to the picture that I’ve attach below
We can set up an equation: x * (x + 5) = 564, where x is the length of the rectangle we are trying to solve. Using the quadratic formula to solve this, we eventually come up with approximately 21.38 as a value for x. We can verify this by typing 21.38 * (21.38 + 5) into a calculator and seeing that it approximately equals 564.
275 x .20 = 55
You will save $55 with the discount and the new price would be $220.
That would be 5/8
