Finding the Area of Triangles and Parallelograms

What is the formula for the area of a rectangle?

• Length + Width

• Base x Height

• Base + Height

• 1/2 Base x Height

How is the height defined when calculating the area of a triangle?

• The longest side

• Perpendicular to the base

• The slanted side

• Any side of the triangle

In a parallelogram, which sides can be considered as the base for area calculation?

• Only the horizontal sides

• The longest side only

• Any side of the parallelogram

• Only the vertical sides

What happens if the height of a parallelogram extends outside the shape?

• The base is extended to meet the height

• It is ignored in calculations

• Only the inside height is considered

• The area cannot be calculated

How do you calculate the area of a triangle?

• 1/2 (Base + Height)

• Base x Height

• 1/2 Base x Height

• Base + Height

Why is it important to use consistent units when calculating area?

• To simplify the calculation

• To avoid errors in the final result

• Units do not affect the calculation

• To make it easier to remember the formula

How do you handle different units when calculating the area of a shape?

• Choose the unit that gives the largest area

• Calculations are unit-independent

• Use the largest unit for all measurements

• Convert all measurements to the same unit

What is the area of a triangle with a base of 8 cm and height of 10 cm?

• 40 cm squared

• 80 cm squared

• 18 cm squared

• 20 cm squared

What method is used to find the area of irregular shapes?

• Estimation

• Decomposition into smaller regular shapes

• Multiplication of all sides

• Using advanced calculus

What is the area of a square if one side is 6 inches?

• 24 square inches

• 18 square inches

• 12 square inches

• 36 square inches
