Explanation:

Step1: Count length of base

Count the number of grid - units along the base of the rectangle. The base is 4 units long.

Step2: Count length of height

Count the number of grid - units along the height of the rectangle. The height is 6 units long.

Step3: Apply area formula

The area formula for a rectangle (a type of quadrilateral) is $A = b\times h$, where $b$ is the base and $h$ is the height. So $A=4\times6$.
$A = 24$

Answer:

A. 24
