Understanding Areas of Parallelograms and Triangles

What defines the height of a shape?

• The longest side of the shape

• The distance around the shape

• The area of the shape

• The length perpendicular from the base to the top

What makes a parallelogram different from a rectangle?

• Rectangles have opposite sides that are not parallel

• Parallelograms have opposite sides that are parallel and congruent

• Rectangles have sides of equal length

• Parallelograms have four right angles

How do you find the area of a parallelogram?

• Length plus width

• Base times height

• Length times width

• Base plus height

If a parallelogram has a base of 15 feet and a height of 6 feet, what is its area?

• 45 square feet

• 30 square feet

• 90 square feet

• 21 square feet

What is the formula for the area of a triangle?

• Half the base plus height

• Length times width divided by 2

• Base times height divided by 2

• Base times height

How can the area of a triangle be expressed using the base and height?

• Area equals half times the base times the height

• Area equals the base plus the height

• Area equals the base times the height

• Area equals two times the base times the height

For a triangle with a base of 10 inches and a height of 8 inches, what is its area?

• 40 square inches

• 80 square inches

• 20 square inches

• 18 square inches

What is the area of a parallelogram with a base of 12 meters and a height of 4 meters?

• 48 square meters

• 24 square meters

• 16 square meters

• 8 square meters

If the area of a triangle is 35 square units and the base is 10 units, what is the height?

• 3.5 units

• 14 units

• 7 units

• 70 units

How do you find the unknown base of a parallelogram if you know its area and height?

• Subtract the height from the area

• Add the area to the height

• Multiply the area by the height

• Divide the area by the height
