What does the perimeter of a shape represent?

• The number of sides the shape has.

• The total distance around the shape.

• The length of the longest side.

• The area inside the shape.

Which formula is used to calculate the distance between two points?

• Pythagorean Theorem

• Slope Formula

• Distance Formula

• Midpoint Formula

When applying the distance formula, what is important to remember?

• Always subtract the smaller coordinate from the larger one.

• Use the same order for subtracting coordinates.

• Only subtract the x-coordinates.

• Only subtract the y-coordinates.

What is the result of adding all the calculated distances of the quadrilateral's sides?

• The perimeter of the quadrilateral.

• The average side length of the quadrilateral.

• The area of the quadrilateral.

• The diagonal length of the quadrilateral.
