Question

sanji has a square room with a perimeter of 42.5 feet. if she wants to hang a curtain along one full side of the room, how long does the curtain need to be?
a. 8.25 ft
b. 10.625 ft
c. 21.25 ft
d. 38.5 ft

Explanation:

Step1: Recall the perimeter formula for a square

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

Step2: Solve for the side length \( s \)

We know \( P = 42.5 \) feet. From \( P = 4s \), we can solve for \( s \) by dividing both sides of the equation by 4: \( s=\frac{P}{4}\). Substituting \( P = 42.5 \) into the formula, we get \( s=\frac{42.5}{4}\).

Step3: Calculate the value of \( s \)

\( \frac{42.5}{4}=10.625 \) feet.

Answer:

B. 10.625 ft
