Question

The width of a rectangle is 7 meters greater than its length. If the area of the rectangle is 170 square meters, write the quadratic equation in standard form for the equation that would represent the area of the rectangle. Let x equal the length of the rectangle.

Answer 1

Answer: x² + 7x - 170 = 0

Answer 2

Let the length be x.
Length = x
Width = x + 7

Area = Length x Width = x (x + 7)

x(x + 7) = 170

x² + 7x - 170 = 0

Answer: x² + 7x - 170 = 0
