Question

which expression shows a way to find the area of the following rectangle?
choose 1 answer:
a ( 4 \times 4 )
b ( 5 \times 4 )

Explanation:

Step1: Count the number of columns

The rectangle has 4 columns.

Step2: Count the number of rows

The rectangle has 5 rows.

Step3: Use the area formula for a rectangle

The area of a rectangle is \( \text{length}\times\text{width}\), here the number of rows and columns can be considered as length and width. So the area is \(5\times4\).

Answer:

B. \(5\times4\)
