Understanding Area in Geometry

What is area?

• A 1-dimensional quantity

• The perimeter of a shape

• A 2-dimensional quantity covering the surface of a shape

• The volume of a shape

What unit is used to measure a small area?

• Square meter

• Square centimeter

• Cubic centimeter

• Meter

How do you calculate the area of a rectangle?

• Length plus width

• Length times width

• Length divided by width

• Width minus length

What does 'cm squared' signify?

• Cubic centimeters

• A measurement of area

• Centimeters divided by two

• A measurement of volume

Can a non-square shape have an area of 1 square centimeter?

• Yes, if it covers the same surface area as a square centimeter

• No, only squares can have square centimeters

• Yes, but only for triangles

• No, because it's not a square

What formula is used to calculate the area of a triangle?

• Base plus height

• Base divided by height

• One-half base times height

• Base times height

Why do we use 'base' and 'height' instead of 'length' and 'width' for triangles?

• Because it's a traditional method

• To accommodate different types of triangles

• Because triangles don't have length and width

• To make the calculation easier

How is the area of an acute triangle calculated?

• One-half base times height

• Using the perimeter

• Length times width

• Base times height divided by two

What is the area of a triangle with a base of 4 inches and a height of 7 inches?

• 21 square inches

• 14 square inches

• 28 square inches

• 11 square inches

Can the formula for the area of a triangle be applied to all types of triangles?

• Yes, for all types

• No, only for right triangles

• No, only for acute triangles

• Yes, but with modifications for obtuse triangles
