The rectangle below has an area of x^2-x-72x 2
−x−72x, squared, minus, x, minus, 72 square meters and a length of x+8x+8x, plus, 8 meters.
What expression represents the width of the rectangle?

\text{Width} =Width=start text, W, i, d, t, h, end text, equals
meters

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

12.5 feet
