Question

what is the perimeter of this rectangle?
2 km
38 km
blank kilometers

Explanation:

Step1: Recall the perimeter formula for a rectangle.

The formula for the perimeter \( P \) of a rectangle is \( P = 2\times (length + width) \). Here, the length is \( 38 \) km and the width is \( 2 \) km.

Step2: Substitute the values into the formula.

First, calculate the sum of length and width: \( 38 + 2 = 40 \) km. Then, multiply by 2: \( 2\times40 = 80 \) km.

Answer:

80
