Question

rectangle is by covering it with unit squares
which expression represents the area of
this square?
4·4
what is the area of this square?
a = \square square units
\square = 1 square unit

Explanation:

For the expression representing the area of the square:

Step1: Identify the side length

From the diagram, the square has a side length of 4 units (since there are 4 unit squares along each side).

Step2: Recall the area formula for a square

The area \( A \) of a square is given by the formula \( A = s \times s \), where \( s \) is the side length. Here, \( s = 4 \), so the expression for the area is \( 4 \times 4 \).

For the area of the square:

Step1: Use the area formula for a square

We know the side length \( s = 4 \) units. The area formula for a square is \( A = s \times s \).

Step2: Substitute the value of \( s \)

Substituting \( s = 4 \) into the formula, we get \( A = 4 \times 4 \).

Step3: Calculate the product

\( 4 \times 4 = 16 \).

Answer:

(expression for area):
\( 4 \times 4 \)
