Basic Geometry Formulas

What is the formula for the area of a rectangle?

• Area = length + width

• Area = length × width

• Area = length - width

• Area = length / width

What is the difference between area and perimeter?

• Area measures the distance around a shape; perimeter measures the space inside a shape.

• Area measures the space inside a shape; perimeter measures the distance around a shape.

• Area and perimeter are the same; they both measure the space inside a shape.

• Area measures the volume of a shape; perimeter measures the distance around a shape.

What is the formula for the volume of a rectangular prism?

• Volume = length + width + height

• Volume = length × width × height

• Volume = length × height × depth

• Volume = width × height × depth

What is the perimeter of a rectangle?

• Perimeter = length × width

• Perimeter = 2 × (length + width)

• Perimeter = length + width

• Perimeter = 2 × (length - width)

How do you find the area of a trapezoid?

• Area = base × height

• Area = 1/2 × (base1 + base2) × height

• Area = (base1 + base2) × height
