Question

find the perimeter. 8 m 2 m p = ? m

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \( P \) of a rectangle is \( P=2\times(\text{length}+\text{width}) \). Let \( l = 8\space m \) (length) and \( w = 2\space m \) (width).

Step2: Substitute the values into the formula

Substitute \( l = 8 \) and \( w = 2 \) into \( P = 2\times(l + w) \). So \( P=2\times(8 + 2) \).

Step3: Simplify the expression inside the parentheses first

\( 8+2=10 \). Then \( P = 2\times10 \).

Step4: Calculate the final result

\( 2\times10 = 20 \).

Answer:

20
