How can you identify a trapezoid?

• It has two sets of parallel sides

• It is a three-sided figure

• It has one set of parallel sides

• It has no parallel sides

What is important to remember about the sides of a rectangle?

• Only one side is equal to another

• All sides are equal

• Opposite sides are equal

• All sides are different

What is the formula for the area of a rectangle?

• Base times height divided by two

• Base plus height

• Length plus width

• Length times width

How do you find the area of a composite shape?

• By subtracting the areas of individual shapes

• By adding the areas of individual shapes

• By multiplying the areas of individual shapes

• By dividing the areas of individual shapes

What is the first step in finding the area of a shaded region?

• Add the area of the triangle to the rectangle

• Subtract the area of the triangle from the rectangle

• Multiply the area of the triangle by the rectangle

• Divide the area of the triangle by the rectangle

What is the formula for the area of a triangle?

• Base times height

• Base times height divided by two

• Length times width

• Base plus height

Why is it important to show your work in geometry?

What should you do if a shape looks like a square but isn't?

• Assume it is a square

• Ignore the given dimensions

• Change the dimensions to fit a square

• Go with the given dimensions

What is the final step in calculating the area of a shaded region?

• Add the areas of all shapes

• Divide the unwanted area by the total

• Subtract the unwanted area from the total

• Multiply the areas of all shapes
