Exploring the Area of Parallelograms

What defines a shape as a parallelogram?

• Four equal sides

• All sides are perpendicular

• All angles are equal

• Two pairs of parallel sides

How should the height of a parallelogram be measured?

• Diagonally across the shape

• Parallel to the base

• Along the longest side

• Perpendicular to the base

What was the estimated area of the parallelogram in the exercise?

• 50 square units

• 60 square units

• 70 square units

• 80 square units

How many units long is the base of the parallelogram discussed?

• 12 units

• 5 units

• 6 units

• 10 units

What is the height of the parallelogram in centimeters?

• 10 cm

• 6 cm

• 12 cm

• 5 cm

What analogy is used to explain the rearrangement of the parallelogram?

• Shuffling books on a shelf

• Rearranging body parts

• Changing tires on a car

• Moving rooms in a house

Does rearranging parts of the parallelogram change its area?

• It depends on the shape

• Yes, it decreases

• Yes, it increases

• No, it stays the same

What is the formula for the area of a parallelogram?

• Length x Width

• Base x Height

• 2 x (Base + Height)

• Base + Height

If the base is 10 cm and the height is 6 cm, what is the area?

• 100 square cm

• 60 square cm

• 16 square cm

• 30 square cm

Why is the area not halved when calculating for a parallelogram?

• Because it is always a square

• Because it has two bases

• Because no material is removed during rearrangement

• Because the shape is not symmetrical
