The length of a rectangle is 3 feet less than 4 times the width of the perimeter is 144 feet find the length and the width of the rectangle
Let the width of the rectangle be x.
The length of the rectangle is 4x - 3.
The perimeter of the rectangle is 2x + 2(4x - 3) = 144 feet.
This simplifies to 2x + 8x - 6 = 144.
Combining like terms, we get 10x - 6 = 144.
Adding 6 to both sides, we get 10x = 150.
Dividing both sides by 10, we get x = 15.
The width of the rectangle is x = 15 feet.
The length of the rectangle is 4(15) - 3 = 57 feet.
Therefore, the length of the rectangle is 57 feet and the width of the rectangle is 15 feet.
