Question 1024336: The perimeter of rectangle ABCD is 42 cm and the area is 80 cm^2. Which equation can be used to find the dimensions of the rectangle? (Hint: Set up a system of equations).
xy + 2x + 2y = (42)(80)
x2 + 80x - 42 = 0
x2 - 42x + 80 = 0
x2 - 21x + 80 = 0 Found 2 solutions by ikleyn, Fombitz:Answer by ikleyn(52778) (Show Source):
