Geometry Concepts and Formulas

This video tutorial by Parker from Test Prep Champions covers how to find the perimeter and area of various shapes needed for the GED test. It begins with an introduction to perimeter, explaining its definition and formulas for squares, rectangles, and triangles. The tutorial then shifts to area, discussing its concept and calculation for squares, rectangles, parallelograms, triangles, and trapezoids. The video includes examples and problem-solving strategies, emphasizing understanding and application of formulas.

What is the perimeter of a shape?

• The distance around a shape

• The area inside a shape

• The volume of a shape

• The diagonal of a shape

How can you calculate the perimeter of a square if one side is 5 units?

• 5 x 4

• 5 + 5 + 5 + 5

• 5 x 5

• 5 + 4

Which formula can be used to find the perimeter of a rectangle?

• P = 2l + 2w

• P = l + w

• P = l x w

• P = 2(l + w)

If a triangle has sides of 3, 4, and 5 units, what is its perimeter?

• 10 units

• 9 units

What is the area of a shape?

• The width of a shape

• The length of a shape

• The space inside a shape

• The distance around a shape

How do you calculate the area of a square with a side length of 6 units?

• 6 + 4

• 6 x 6

• 6 x 4

• 6 + 6

What is the formula for the area of a rectangle?

• Area = length x width

• Area = length x 2

• Area = length + width

• Area = 2(length + width)
