Finding Base and Height in Parallelograms

This video tutorial explains how to find the base or height of a parallelogram given its area. It begins with a recap of the area formula, which is the base multiplied by the perpendicular height. The video then illustrates the concept of perpendicular height and how it relates to the base. Finally, it applies the formula to solve a problem, demonstrating how to calculate the height when the area and base are known, using division to find the solution.

What is the main topic of this video tutorial?

• Understanding the properties of circles

• Finding the base or height of a parallelogram given its area

What is the relationship between base, height, and area in a parallelogram?

• Area is the sum of base and height

• Area is the product of base and height

• Area is the quotient of base and height

• Area is the difference between base and height

In a parallelogram, can the base be non-horizontal?

• Yes, the base can be any side

• No, the base must always be horizontal

• No, the base must be the longest side

• Yes, but only if the height is vertical

How do you identify the perpendicular height in a parallelogram?

• It is the longest side

• It is the diagonal of the shape
