Finding the Area of Rectangles and Squares

Jared draws a rectangle. Which equation shows how to find the area using the Distributive Property?

• (5 x 3) + (5 x 3) = 30

• (5 x 4) + (5 x 4) = 40

• (5 x 4) + (5 x 5) = 45

• (2 x 3) + (4 x 5) = 26

How can the area of this rectangle be found?

• Add the number of sides and the number of vertices.

• Add the number of sides to the number of rows.

• Multiply the number of squares by the number of sides.

• Count the total number of squares.
