Exploring Area of Parallelograms Concepts

The video tutorial explains how to find the area of a parallelogram using a grid, focusing on identifying the base and height. It provides examples of calculating the area when the base is diagonal and when dealing with shaded regions by subtracting the area of a rectangle. The tutorial emphasizes the importance of making a 90-degree angle for height measurement and offers practical examples to reinforce the concepts.

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

• Length x Width

• Perimeter x Area

• Base x Height

• Side x Diagonal

If a parallelogram's base is 12 units and height is 5 units, what is its area?

• 17 square units

• 50 square units

• 30 square units

• 60 square units

Can the height of a parallelogram be drawn outside the figure?

• No, unless specified

• Yes, if it is parallel to the base

• No, it must be inside

• Yes, if it forms a 90-degree angle with the base

What should be considered when choosing the base of a parallelogram for area calculation?

• It must be the shortest side

• It should be a side that is horizontal or vertical on the grid

• Any side can be the base

• It must be the longest side

In a real-life scenario, how would you calculate the remaining area of a backyard after installing a pool?

• Multiply the areas of the backyard and the pool

• Divide the area of the backyard by the area of the pool

• Add the area of the pool to the total area

• Subtract the area of the pool from the total area of the backyard

What is the area of a backyard that is 80 feet by 50 feet?

• 4000 square feet

• 1300 square feet

• 2500 square feet

• 3200 square feet

What is the area of a rectangle with a base of 40 feet and height of 30 feet?

• 1200 square feet

• 1000 square feet

• 700 square feet

• 1500 square feet

How do you find the area of a shaded region within a parallelogram?

• Multiply the total area by the shaded percentage

• Subtract the area of the shaded part from the total

• Subtract the area of the non-shaded part from the total

• Add the area of the shaded part to the total

If a rectangle is removed from a parallelogram, how do you calculate the remaining area?

• Divide the parallelogram's area by the rectangle's area

• Add the rectangle's area to the parallelogram's area

• Subtract the rectangle's area from the parallelogram's area

• Multiply the parallelogram's area by the rectangle's area

If a parallelogram has a base of 10 units and a height of 7 units, what is its area?

• 17 square units

• 50 square units

• 100 square units

• 70 square units
