Finding Area of a Rhombus

The video explains how to find the area of a rhombus by drawing a rectangle around it. Calvin suggests this method, and the video demonstrates the process of drawing the rectangle and using it to calculate the rhombus's area. The key idea is that the area of the rectangle can be adjusted to match the rhombus by rearranging parts of the shape.

What is the initial step Calvin suggests for finding the area of a rhombus?

• Drawing a circle around the rhombus

• Measuring the angles of the rhombus

• Composing a rectangle around the rhombus

• Calculating the perimeter of the rhombus

What is the special method used to draw the rectangle around the rhombus?

• Using the height of the rhombus

• Using the base of the rhombus

• Using the diagonal of the rhombus

• Using the perimeter of the rhombus

How does the rectangle help in finding the area of the rhombus?

• By calculating the perimeter of the rectangle

• By rearranging parts of the rectangle to match the rhombus

• By measuring the angles of the rectangle

• By using the diagonal of the rectangle

What characteristic of the rhombus is crucial for using the rectangle to find its area?

• The perimeter is known

• All angles are right angles

• The diagonals are equal

• All sides are equal

What happens to the rectangle when parts of it are rearranged?

• It forms a square

• It becomes larger than the rhombus

• It becomes smaller than the rhombus

• It matches the area of the rhombus
