Answer

\text{7 cm}

3 steps

To find the length of the rectangle, we use the formula for the perimeter of a rectangle:

P = 2(L + W)

Where:

Identify the given values.
The perimeter $P = 24 \text{ cm}$ .
The width $W = 5 \text{ cm}$ .
Substitute the given values into the perimeter formula.
$24 = 2(L + 5)$
Solve the equation for $L$ .
First, divide both sides by 2:
$\frac{24}{2} = L + 5$ $12 = L + 5$
Next, subtract 5 from both sides to isolate $L$ :
$12 - 5 = L$ $7 = L$
The length of the rectangle is $\text{7 cm}$ .
