Please help.. what is the function rule for the perimeter P of a building with a rectangular base if the width w is two times the length L?

A.) P=2L B.) P=6L C.) P=6w

For the answer to the question above, this is the formula for finding the rectangular base.
P = 2L + 2WConsider the Width being twice as long as the length. If we write it down, it will look like thisW= 2 LWe'll plug that into the perimeter equation,P = 2L + 2W→ P = 2L + 2(2L)Now, just simplify the equation and problem is solved.
I hope I helped you with my answer.

Answer:

B.) P = 6L

Step-by-step explanation:

The perimeter is the sum of all sides of the figure. In this case, the perimeter of the rectangle would be: \(P=W+L+W+L\); where \(W\) is width, and \(L\) is length.

According to the problem, the width is two times the length:

\(W=2L\)

Replacing this relation in the perimeter equation, we have:

\(P=2W+2L\\P=2(2L)+2L\\P=4L+2L\\P=6L\)

Therefore, the perimeter is six times the length of the rectangle. The correct answer is B.
