Area and Height of Parallelograms

This video tutorial covers the process of drawing and labeling the height of parallelograms, finding the height using perpendicular lines, and calculating the area using base and height. It includes methods for multiplying decimals and using fractions to find the area, converting improper fractions to mixed numbers, and comparing the areas of rectangles and parallelograms. The tutorial also demonstrates solving equations to determine unknown heights.

What is the first step in drawing the height of a parallelogram?

• Find a perpendicular line from the base

• Draw a diagonal line

• Measure the angles

• Extend the sides

How do you find the height of a parallelogram?

• By drawing a perpendicular line from the base to the opposite side

• By measuring the angles

• By measuring the longest side

• By calculating the area

What is the formula for calculating the area of a parallelogram?

• Base minus height

• Base divided by height

• Base times height

• Base plus height

If the base of a parallelogram is 13 cm and the height is 6 cm, what is the area?

• 78 cm²

• 39 cm²

• 19 cm²

• 65 cm²

In the example with mixed numbers, what is the first step in calculating the area?

• Convert to improper fractions

• Add the numbers

• Subtract the numbers

• Multiply directly

How can a rectangle and a parallelogram have the same area?

• By having the same perimeter

• By having the same diagonal length

• By having the same base and height

• By having the same angles

What equation relates the area, base, and height of a parallelogram?

• Area = base - height

• Area = base ÷ height

• Area = base × height

• Area = base + height

If a parallelogram has an area of 20.3 cm² and a base of 2.5 cm, how do you find the height?

• Subtract the base from the area

• Add the base to the area

• Divide the area by the base

• Multiply the area by the base
