Question

The perimeter of the rectangle is unknown. The length is x + 4 ft, while the width is 2x ft. The area is unknown. What is the perimeter?

Answer 1

Answer:

6x + 8 feet.

Step-by-step explanation:

The perimeter of a rectangle is equal to two times the height, plus two times the base. In this case, one side is given as x + 4 feet, and the other as 2x feet.

So, simply multiply each side by two, and add them together.

(2)(x + 4) + (2)(2x)

2x + 8 + 4x = 6x + 8 feet
