8 mia measures a bicycle, which is equal to the length of 3 sticks. each stick is 2 feet long. how long is mia’s bicycle?

Explanation:

Step1: Count rows and columns

The rectangle has 3 rows and 4 columns of unit - squares.

Step2: Use area formula

The area of a rectangle is $A = \text{length}\times\text{width}$. Here, the number of unit - squares in length is 4 and in width is 3. So $A=3\times4 = 12$.

A. 12 square inches
