Answer: 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.
