Question

the diagram shows how sergio can cut the parallelogram? what is the area of the rectangle sergio makes? area of rectangle =? square units

Explanation:

Step1: Count the length and width of the rectangle

From the grid, the length of the rectangle is \( 5 \) units and the width is \( 4 \) units.

Step2: Use the formula for the area of a rectangle

The formula for the area of a rectangle is \( A = l\times w \), where \( l \) is the length and \( w \) is the width. Substituting \( l = 5 \) and \( w = 4 \), we get \( A=5\times4\).

Answer:

\( 20 \)
