Question

find the perimeter. 54 cm 36 cm p =? cm

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \( P \) of a rectangle is \( P = 2\times(\text{length}+\text{width}) \). Here, the length \( l = 54\space\text{cm} \) and the width \( w = 36\space\text{cm} \).

Step2: Substitute the values into the formula

Substitute \( l = 54 \) and \( w = 36 \) into \( P = 2\times(l + w) \). So, \( P=2\times(54 + 36) \).
First, calculate the sum inside the parentheses: \( 54+36=90 \).
Then, multiply by 2: \( P = 2\times90 \).

Step3: Calculate the final result

\( 2\times90=180 \).

Answer:

\( 180 \)
