The area of a rectangle is 70 in² and the length of the rectangle is 3 in. longer than the width. the area of a rectangle is found by multiplying the length times the width. during the set up step of the five-step problem-solving plan, which equation would you set up to solve for the width

Step-by-step explanation:

Let w be the width of the rectangle.

We have been given the length of the rectangle is 3 in. longer than the width. So the length of the rectangle would be .

We are also told that the area of a rectangle is 70 in². We know that area of rectangle in length times width. We can represent the given information in an equation as:

Therefore, the equation can be used to find the width of the rectangle.
