Question

which expression represents the area of this square? 4 + 4, 2 + 4, 2 · 4, 4 · 4. (there is a square grid image on the right, and a small square with the note “= 1 square unit” below the grid.)

Explanation:

Step1: Determine side length of square

The square is made of unit squares. By counting, each side has 4 unit squares, so side length \( s = 4 \).

Step2: Recall area formula for square

The area of a square is given by \( A = s \cdot s \). Substituting \( s = 4 \), we get \( A = 4 \cdot 4 \).

Answer:

\( 4 \cdot 4 \)
