Look at the composite figure. How could you find the perimeter of the figure?

• Add the four side lengths shown in the diagram.

• Divide the figure into two rectangles. Find the perimeter of each rectangle. Add the two perimeters.

• Find the two missing side lengths and add them to the four side lengths shown in the diagram.

• Multiply the four side lengths shown in the diagram.

Look at the figure below.  What method could be used to find the area of the two-dimensional figure?

• Find the area of the trapezoid, find the area of the rectangle, and then subtract the areas.

• Find the area of the trapezoid, find the area of the rectangle, and then multiply the areas.

• Find the area of the trapezoid, find the area of the rectangle, and then divide the areas.

• Find the area of the trapezoid, find the area of the rectangle, and then add the areas.

What do you do if they ask you to find the area of ONLY the SHADED part? 

• Find the area of the shaded, find the area of the not shaded, and then ADD the shaded with the not shaded
