Understanding the Area of a Rhombus

The video tutorial explains how to find the area of a rhombus using two methods. The first method involves using the base and the altitude height, similar to calculating the area of a rectangle. The second method uses the lengths of the diagonals, where the area is half the product of the diagonals. Both methods are demonstrated with examples, and the importance of using the correct measurements is emphasized.

What is the first method to find the area of a rhombus?

• Using base and height

• Using the length of one side

• Using the radius

• Using the perimeter

Why can't the side of a rhombus be used as the height in the area calculation?

• Because the side is not visible

• Because the side is not a straight line

• Because the side is too long

• Because the side is not perpendicular to the base

What is the second method to find the area of a rhombus?

• Using the diagonals

• Using the perimeter

• Using the side length

• Using the radius

How do you calculate the area of a rhombus using diagonals?

• Multiply the diagonals and add two

• Multiply the diagonals and divide by two

• Add the diagonals and multiply by two

• Subtract the diagonals and divide by two

What is the area of a rhombus with diagonals measuring 10 and 14?

• 70 square units

• 140 square units

• 120 square units

• 100 square units

What is the product of the diagonals in the example given?

• 120

• 100

• 140

• 70

What is the result of dividing the product of the diagonals by two in the example?

• 70

• 140

• 120

• 100

Which method requires knowing the altitude of the rhombus?

• Radius method

• Diagonal method

• Perimeter method

• Base and height method

Which method is more straightforward if the diagonals are known?

• Perimeter method

• Radius method

• Diagonal method

• Base and height method

What is the key takeaway from the tutorial?

• Only the diagonal method is correct

• Only the base and height method is correct

• Neither method is useful

• Both methods are useful depending on the information available
