Question

what is the perimeter of this rectangle? 12 cm 5 cm 5 cm 12 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 \( l = 12\space\text{cm} \) and the width \( w = 5\space\text{cm} \).

Step2: Substitute the values into the formula

Substitute \( l = 12 \) and \( w = 5 \) into \( P = 2\times(l + w) \). So \( P=2\times(12 + 5) \).
First, calculate the sum inside the parentheses: \( 12+5=17 \).
Then, multiply by 2: \( P = 2\times17 \).

Step3: Calculate the final result

\( 2\times17=34 \).

Answer:

\( 34 \)
