The length of a rectangle is 7 yards less than 4 times the width, the perimeter is 56 yards, how do you find the length and the width of the rectangle?
The width is 7 yards and the length is 21 yards.
First, let's define our variables.
From the information provided we know the relationship between the length and the width:
The formula for the perimeter of a rectangle is:
We know the perimeter of the rectangle and we know the length in terms of the width so we can substitute these values into the formula and solve for the width:
Now that we know the width is
