The length of a rectangle is 3 less than 2 times the width If the area is 77 square inches what is the length of the rectangle?
Let the length be l, the width be w, and the area be A. The equation for the area of a rectangle is A = l*w; we know A = 77, so we need to get l in terms of w so we only have one variable to solve for. We're given l = 2w-3, so we can substitute back in:
A=77=(2w-3)*w
77=2w^2-3w
0=2w^2-3w-77
0=(2w+11)*(w-7)
so w=-5.5 or w=7. Since we can't have a negative width, w=7 inches. Plugging back in to our equation for l and w: l=2w-3=2(7)-3=14-3=11, so the length is 11 inches.

The length of a rectangle is 2 inches more than its width the area of the rectangle is 15 square inches what are the length and width of the rectangle?
Call the width of the rectangle x. Call the length of the rectangle x + 2. The area of the rectangle would be the length times the width. We know this is 15 square inches. Set up the equation and solve for x. (x +2)x = 15 x2 + 2x = 15 x2 + 2x - 15 = 0 Factor the quadratic equation: (x - 3)(x + 5) = 0 x = 3 or x = -5 Since length can't be negative, discard the answer -5. If x = 3, then the width is 3 and the length is x + 2 or 5. 5 x 3 = 15 which equals the area.
