Geometry Concepts and Problem Solving

The video tutorial covers the geometry section of the TSI exam, emphasizing the importance of understanding area and perimeter formulas. It explains how algebra is often integrated into geometry questions, providing strategies for solving such problems. Two example problems are discussed: one involving rows of trees in a rectangular parcel and another about calculating the area of a yard given its perimeter. The tutorial highlights the need to recognize area questions and use given information effectively.

What are the two main types of formulas you need to know for the geometry section of the TSI?

• Circumference and Diameter

• Volume and Surface Area

• Slope and Intercept

• Area and Perimeter

How does the TSI often incorporate algebra into geometry questions?

• By using complex numbers

• By mixing algebraic expressions with geometry problems

• By focusing solely on algebra

• By avoiding algebra completely

In the example problem, what is the expression for the number of trees in each row?

• 3x + 2

• 3x - 2

• 2x + 3

• x - 3

What is the total expression for the number of trees in the parcel?

• 16x - 24

• 16x + 24

• 24x - 16

• 24x + 16

What mathematical operation is usually indicated by the word 'each' in a problem?

• Subtraction

• Addition

• Division

• Multiplication

What is the correct number of rows of trees in the parcel?

• 7

• 9

• 6

• 8

What is the perimeter of Cindy's yard?

• 80 feet

• 64 feet

• 72 feet

• 90 feet

How is the perimeter of a rectangle calculated?

• Length - Width

• Length * Width

• 2 * (Length + Width)

• Length + Width

If the length is 18 feet longer than the width, what is the expression for the length?

• 18 - Width

• Width - 18

• Width + 18

• 18 + Width

What is the width of the rectangle if the perimeter is 72 feet?

• 12 feet

• 18 feet

• 15 feet

• 9 feet
