Exploring Area and Perimeter of Parallelograms and Triangles

What is the perimeter?

• The space inside a figure

• The distance around a figure

• The length of one side of a figure

• The width of a figure

What does the perimeter measure?

• Square units inside a figure

• Cubic units inside a figure

• Volume of a figure

• Linear distance around a figure

How do you calculate the area of a rectangle?

• (Length + Width) x 2

• Length / Width

• Length x Width

• Length + Width

What units are used to measure area?

• Linear units

• Square units

• Kilograms

• Cubic units

What is the correct way to label the area of a figure?

• In linear units

• In cubic units

• No units

• In square units

What is the formula for the area of a parallelogram?

• (Base + Height) x 2

• Base x Height

• Base + Height

• Base / Height

How is the perimeter of a parallelogram calculated?

• Base + Height

• Adding all sides together

• Base x Height

• (Base + Height) x 2

What property do opposite sides of a parallelogram have?

• Both B and C

• They are congruent

• They are parallel

• They are perpendicular

What is the area of a triangle formula?

• (Base x Height) / 2

• 1/2 x Base x Height

• Base + Height

• Base x Height

Why is the area of a triangle half the area of a parallelogram?

• Because it has a different shape

• Because it is half of a parallelogram when divided by a diagonal

• Because it is always smaller

• Because it has fewer sides
