The perimeter of a rectangle is 136 feet. The length is seven feet less than four times the width. Find the length and width.
Step 1. Let l = 4w-7 length of rectangle and let w be the width. And we are given that length is seven feet less than 4 times the width.
Step 2. Let P = 136 ft be the perimeter. Perimeter means adding the 4 sides of a rectangle. So,
Step 3. Add 14 to both sides of equation to get 4w by itself
Step 4. Divide 10 to both sides of equation
Step 5. w = 15 is the width of the rectangle and length is 53 since
Check P=10w-14=10(15)-14=136 So w = 15 ft and l = 53 ft is the solution.
