Question

11 if a square has a side equal to 5 cm, what will the squares perimeter be if the side is doubled? 40 cm 20 cm 25 cm 80 cm skip 11/12 translate

Explanation:

Step1: Recall perimeter formula

The perimeter formula for a square is $P = 4s$, where $s$ is the side - length of the square.

Step2: Identify new side - length

The side of the square is doubled. The original side $s = 5$ cm, so the new side $s_{new}=2\times5 = 10$ cm.

Step3: Calculate new perimeter

Substitute $s_{new}=10$ cm into the perimeter formula $P = 4s$. So $P = 4\times10=40$ cm.

Answer:

40 cm
