Question

Two rectangles have the same width. The length of one is 2 feet longer than the width. The length of the other is 4 feet longer than the width. The larger rectangle has 8 more square feet than the smaller. What is the width of the rectangles?

Answer 1

1st rectangle area: 2+x*x
=x^2 +2

2nd rectangle area: 8(x^2+4)

-7x= 30
X= -30/7

X= width
