Question

look at this rectangle. find the value of p. perimeter = 70.8 kilometers p = kilometers 15.2 km

Explanation:

Step1: Recall the perimeter formula for a rectangle

The perimeter \( P \) of a rectangle is given by the formula \( P = 2\times (length + width) \). Let the length be \( p \) and the width be \( 15.2 \) km, and the perimeter \( P = 70.8 \) km. So we have the equation \( 70.8 = 2\times (p + 15.2) \).

Step2: Solve for \( p \)

First, divide both sides of the equation by 2:
\( \frac{70.8}{2}=p + 15.2 \)
\( 35.4=p + 15.2 \)

Then, subtract \( 15.2 \) from both sides:
\( p=35.4 - 15.2 \)
\( p = 20.2 \)

Answer:

\( 20.2 \)
