Question

The area of a rectangle is 56 cm squared and the length of the rectangle is 7 cm longer than the width. The area of a rectangle is found by multiplying the length time the width. During the Set Up step for the five-step problem-solving plan, which equation would you set up to solve for the width? w(w+7)=56 W+7=56 7w=56 w+7w=56

Answer 1

Let's call w the width and l the length.

The area of a rectangle is found by multiplying the length time the width, so:

w * l = Area

Additionally, the area of a rectangle is 56, so:

w * l = 56

Finally, the length of the rectangle is 7 cm longer than the width, so:

l = w + 7

w * l = 56

w * (w + 7) = 56

Therefore, the equation that you would set up to solve for the width is:

w(w+7) = 56

Answer: w(w+7)=56
