Question

find the perimeter of the rectangle. use the formula: p = 2l + 2w perimeter = 2 × length + 2 × width l = 5 w = 4 p = ?

Explanation:

Step1: Substitute the values of \( l \) and \( w \) into the formula

Given \( l = 5 \) and \( w = 4 \), substitute into \( p=2l + 2w \).

$$ p=2\times5+2\times4 $$

Step2: Calculate \( 2\times5 \) and \( 2\times4 \)

$$ 2\times5 = 10,\quad 2\times4=8 $$

Step3: Add the results

$$ p=10 + 8 $$

Answer:

\( 18 \)
