Calculating Areas of Shapes

The video tutorial covers the area of triangles, trapezoids, and kites. It begins with a review of previous topics on rectangles and parallelograms, followed by solving review problems involving area and side lengths. The lesson introduces new concepts such as triangle conjecture and area formulas for trapezoids and kites. The tutorial includes examples and practice problems to reinforce learning.

What shapes are being discussed in this lesson for finding their areas?

• Circles, squares, and hexagons

• Triangles, trapezoids, and kites

• Rectangles, circles, and triangles

• Parallelograms, hexagons, and circles

When given the area and base of a rectangle, how can you find the height?

• Multiply the area by the base

• Subtract the base from the area

• Add the area and the base

• Divide the area by the base

In a 30-60-90 triangle, how is the short side related to the hypotenuse?

• It is half the hypotenuse

• It is equal to the hypotenuse

• It is twice the hypotenuse

• It is the same as the long side

What is the formula for the area of a triangle?

• 1/2 base times height

• Base times height

• Base divided by height

• Base plus height

How do you calculate the area of a trapezoid?

• Base times height

• 1/2 times the sum of the bases times the height

• Base plus height divided by two

• Base minus height

What is unique about finding the area of a kite?

• It uses the perimeter

• It uses the diagonals

• It uses the circumference

• It uses the radius

In the example of finding the area of a triangle, what is the base length used?

• 14

• 7

• 8

• 11

When calculating the area of a trapezoid, what is the first step?

• Add the bases

• Divide the bases

• Multiply the bases
