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

length = x
width = x+7
Area = length*width=x(x+7)=x²+7x
x²+7x=170
x²+7x-170=0 usually this for is called standard
