Triangle Area and Quilt Problems

This video tutorial covers Lesson 13.3, focusing on problem-solving using the area of a triangle. It combines skills in solving equations with geometry formulas. The lesson includes examples such as calculating the height of a triangular pennant and the base of a quilt piece. The tutorial also explores alternative methods using fractions for easier calculations.

What is the main focus of lesson 13.3?

• Problem-solving using the area of a triangle

• Solving equations using algebraic expressions

• Understanding the properties of circles

• Learning about the perimeter of polygons

In the Hudson High School problem, what are the given values?

• Height and perimeter

• Base and area

• Height and area

• Base and height

Why might one prefer using fractions over decimals in the Hudson High School problem?

• Fractions are easier to visualize

• Decimals are not allowed in geometry

• Fractions simplify the calculations

• Fractions are more accurate

What is the height of the triangular pennant in the Hudson High School problem?

• 1.5 feet

• 2.25 feet

• 3 feet

• 4 feet

When using decimals, what is the first step to find the height of the triangle?

• Multiply the base by the area

• Add the base and area

• Divide the base by two

• Find half of the base

What is the final height of the triangle when using decimals?

• 3 feet

• 2.25 feet

• 0.75 feet

• 1.5 feet

In Renee's quilt problem, what is the given height of each quilt piece?

• 6 inches

• 7 inches

• 4 inches

• 5 inches

What is the area of each quilt piece in Renee's problem?

• 24 inches squared

• 20 inches squared

• 22 inches squared

• 18 inches squared

What formula is used to find the base of the triangle in Renee's quilt problem?

• Area = base x height

• Area = 1/2 x base x height

• Area = base / height

• Area = base + height

What is the length of the base of each quilt piece in Renee's problem?

• 9 inches

• 6 inches

• 7 inches

• 8 inches
