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

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: ; where is width, and is length.

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

Replacing this relation in the perimeter equation, we have:

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

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
