The length of a rectangle is 4 inches more than the width if the perimeter is 80 inches what are the length and the width
Let's assume that the width of the rectangle is W inches.
Since the length is 4 inches more than the width, the length would be W + 4 inches.
The formula for the perimeter of a rectangle is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.
Substituting the given values, we get 80 = 2(W + 4) + 2W.
Simplifying the equation, we have 80 = 2W + 8 + 2W.
Combining like terms, we get 80 = 4W + 8.
Subtracting 8 from both sides, we get 72 = 4W.
Dividing both sides by 4, we get W = 18.
Thus, the width of the rectangle is 18 inches.
The length is equal to W + 4, so the length is 18 + 4 = 22 inches.
Therefore, the length of the rectangle is 22 inches and the width is 18 inches.
