Question

The length of a rectangle is (x+5) and the width is (x+2). The area of the rectangle is 70 square feet. What is the length of the rectangle?

Answer 1

The length of the rectangle is 30 feet.

Explanation:

Because the equation for area is length times width, you would have to set the two equations to seventy and multiply them.

(x+5) (x+2) = 70

2x + 10 = 70

Then, you would have to subtract ten from both sides, cancelling it from the left side.

2x = 60

Then do the opposite and divide sixty by two, therefore getting a length of thirty feet.
