Understanding the Area of a Rectangle

This video tutorial explains how to calculate the area of a rectangle using the formula area = base x height. It covers examples of finding the area when given the base and height, solving for the base when given the area and height, and using the diagonal and one side to find the area. The tutorial also demonstrates the application of the Pythagorean theorem to solve for unknown sides in a rectangle.

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

• Area = base - height

• Area = base / height

• Area = base * height

• Area = base + height

If a rectangle has a base of 10 units and a height of 8 units, what is its area?

• 18 square units

• 80 square units

• 28 square units

• 100 square units

Given an area of 100 square units and a height of 5 units, what is the base of the rectangle?

• 10 units

• 15 units

• 20 units

• 25 units

What is the first step in solving for the base when given the area and height of a rectangle?

• Divide the area by the height

• Subtract the height from the area

• Add the area and height

• Multiply the area by the height

When given a diagonal and one side of a rectangle, which theorem helps find the missing side?

• Perimeter theorem

• Area theorem

• Volume theorem

• Pythagorean theorem

In a right triangle, if one side is 9 units and the hypotenuse is 15 units, what is the length of the other side?

• 12 units

• 10 units

• 14 units

• 11 units

How do you calculate the area of a rectangle once you have both the base and height?

• Divide the base by the height

• Subtract the base from the height

• Multiply the base and height

• Add the base and height

If a rectangle has a height of 9 units and a base of 12 units, what is its area?

• 120 square units

• 96 square units

• 108 square units

• 100 square units

What is the result of subtracting 81 from 225 in the context of the Pythagorean theorem?

• 164

• 104

• 184

• 144

What is the square root of 144?

• 13
