Question

find the perimeter of the rectangle. include the unit.
15 cm
24 cm

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \( P \) of a rectangle is \( P = 2\times (length + width) \). Here, the length is \( 24 \, \text{cm} \) and the width is \( 15 \, \text{cm} \).

Step2: Substitute the values into the formula

First, calculate the sum of length and width: \( 24 + 15 = 39 \, \text{cm} \). Then, multiply this sum by 2: \( P = 2\times39 = 78 \, \text{cm} \).

Answer:

\( 78 \, \text{cm} \)
