Question

the perimeter of the figure is 26 cm. figure not drawn to scale. what is the length of the missing side?

Explanation:

Step1: Recall perimeter formula

Perimeter = sum of all side - lengths. Let the missing side - length be $x$.

Step2: Set up the equation

$26=7 + 7+4 + 3+x$.

Step3: Simplify the right - hand side

$7 + 7+4 + 3=21$, so the equation becomes $26=21 + x$.

Step4: Solve for $x$

Subtract 21 from both sides: $x=26 - 21$.
$x = 5$.

Answer:

$5$ cm
