2. The area of a rectangle is 56 square inches. The rectangle is 8 inches long. How wide is the rectangle?

A.15 inches

B. 7 inches

C.48 inches

D.20 inches

B. 7 inches

Step-by-step explanation:

The area of a rectangle is given by

A = l*w  where l is the length and w is the width

56 = 8*w

Divide each side by 8

56/8 = 8w/8

7 =w

7 inches

Step-by-step-Explanation: The formula for the area of a rectangle is below shown below.

Area = length · width

Since we know that the area of the rectangle is 56 in² and the length of the rectangle is 8 inches, we have 56 = 8 · w.

Now to find w or the width of the rectangle, we divide

both sides of the equation by 8 to get 7 = w.

So the width of the rectangle is 7 inches.

Notice that we include inches in our final answer because we were given inches as units in the original problem.

Also notice that we don't ever have to draw a picture of the rectangle in this problem. We can find our answer by simply using the formula for the area of a rectangle.
