The school principal is designing a square courtyard outside of the school, separated into 4 equal spaces. She wants to know the total area of the courtyard.

[tex]\[ s = \text{length (ft) of one side of each space.} \][/tex]

Which expression shows the total area of the courtyard?

A. [tex]\( s^2 \)[/tex]
B. [tex]\( s^2 + 4 \)[/tex]
C. [tex]\( s^4 + 4 \)[/tex]
D. [tex]\( 4s^2 \)[/tex]



Answer :

To determine the total area of the courtyard, which is divided into 4 equal spaces, we will proceed with the following steps:

1. Determine the area of one space: Since each space is a square and has a side length of [tex]\( s \)[/tex] feet, we can calculate the area of one space using the formula for the area of a square:
[tex]\[ \text{Area of one space} = s^2 \][/tex]

2. Calculate the total area of the courtyard: The courtyard is divided into 4 equal spaces. Therefore, to get the total area of the courtyard, we need to multiply the area of one space by 4:
[tex]\[ \text{Total area} = 4 \times (\text{Area of one space}) \][/tex]

3. Substitute the area of one space: Substitute the expression [tex]\( s^2 \)[/tex] from the first step into the total area calculation:
[tex]\[ \text{Total area} = 4 \times s^2 \][/tex]

Therefore, the expression that shows the total area of the courtyard is:
[tex]\[ 4 s^2 \][/tex]

Hence, the correct expression is:
[tex]\[ 4 s^2 \][/tex]
