Finding the Missing Side from Area Problems

The video tutorial covers how to find the missing side of a rectangle when given one side and the total area. It begins with a review of area and perimeter concepts, followed by three sample problems demonstrating how to solve for missing dimensions using the area formula. The tutorial concludes with a preview of the next lesson on finding missing sides using perimeter and instructions for a follow-up quiz.

What is the formula for the area of a rectangle?

• Area = Length - Width

• Area = Length * Width

• Area = Length / Width

• Area = Length + Width

How do you start solving for a missing dimension of a rectangle when given the area?

• Multiply the area by the known dimension

• Divide the area by the known dimension

• Add the area to the known dimension

• Subtract the known dimension from the area

What operation is used to find the perimeter of a rectangle?

• Division

• Multiplication

• Addition

• Subtraction

If a rectangle's area is 36 sq ft and the length is 9 ft, what is the width?

• 3 ft

• 9 ft

• 6 ft

• 4 ft

What should you do after writing down the area formula in your notes?

• Write the perimeter formula

• Draw another rectangle

• Erase the formula

• Substitute the known values

What is the length of a rectangle if the area is 40 sq ft and the width is 5 ft?

• 5 ft

• 10 ft

• 8 ft

• 6 ft

If the length of a rectangle is 6 ft and the area is 24 sq ft, what is the width?

• 3 ft

• 4 ft

• 6 ft

• 8 ft

What is the next topic after finding the missing side given the area?

• Finding the missing side given the height

• Finding the missing side given the perimeter

• Finding the missing side given the diagonal

• Finding the missing side given the volume
