Question

unit 1 summative (area/perimeter/volume/surfa find the perimeter of a square with side length 15 cm.
○ 45 cm
○ 75 cm
○ 60 cm
○ 55 cm

Explanation:

Step1: Recall the formula for the perimeter of a square

The perimeter \( P \) of a square is given by the formula \( P = 4 \times s \), where \( s \) is the length of a side of the square.

Step2: Substitute the given side length into the formula

We are given that the side length \( s = 15 \) cm. Substituting this into the formula, we get \( P = 4 \times 15 \).

Step3: Calculate the result

\( 4 \times 15 = 60 \) cm.

Answer:

60 cm (corresponding to the option "60 cm")
