Maddie said the area of a rectangle was 72 square feet. If the length is 9 feet, what is the width of the rectangle?

Answer 1

Hi Maddie,

So the formula for Area of a Rectangle is LENGTH x WIDTH, right? Let's substitute in to see what we have: A=l x w

72=9 x w so to solve this, divide by 9 to both sides.

72/9 = 9w/9 and this gives you

8 = w So the width must be 8 feet. Don't forget the units because most teachers will mark you off.

I hope this helped : )
