Answer:
7 cm
Explanation:
To find the length of the rectangle, we can use the formula for the perimeter of a rectangle:
Perimeter = 2 × Length + 2 × Width
We are given that the width is 5cm and the perimeter is 24cm.
Substituting these values into the formula, we get:
24 = 2L + 2(5)
Simplifying the right side, we get:
24 = 2L + 10
Subtracting 10 from both sides, we get:
14 = 2L
Dividing both sides by 2, we get:
L = 7
Therefore, the length of the rectangle is 7cm.
