Exploring Area Calculations for Triangles and Parallelograms

What is the formula for the area of a triangle?

• Base + Height

• Base x Height

• 1/2 Base x Height

• 2(Base + Height)

What is the term used for the height that is perpendicular in triangles?

• Base height

• Parallel height

• Slant height

• Perpendicular height

How do you calculate the perimeter of a triangle?

• Divide all sides

• Subtract all sides

• Add all sides

• Multiply all sides

In the context of triangles, if the base is not at the bottom, where can it be found?

• Above the height

• Directly under the perpendicular height

• On the left side

• Outside the triangle

What is a parallelogram?

• A shape with all sides equal

• A three-sided shape

• A four-sided shape with opposite sides parallel

• A shape with no parallel sides

What is the area formula for a parallelogram?

• Base x Height

• 1/2 Base x Height

• Base + Height

• 2(Base + Height)

Which shapes are considered special types of parallelograms?

• Circle and Triangle

• Rectangle and Square

• Oval and Circle

• Triangle and Rectangle

How do you find the perimeter of a rectangle?

• Subtract the length from the width

• Add length and width and multiply by 2

• Multiply the length by width

• Add all sides

What does the term 'units squared' signify in area measurement?

• The area does not have units

• The area is measured in cubic units

• The area is measured in square units

• The area is measured in linear units

Why do you need to know the lengths of all sides to calculate the perimeter?

• To add them

• To divide them

• To subtract them

• To multiply them
