Perimeter of Rectangles on Coordinate Plane

Front

What is the formula to calculate the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width)

Front

If a rectangle has a length of 5 units and a width of 3 units, what is its perimeter?

Back

Perimeter = 2 * (5 + 3) = 16 units

Front

What does the term 'coordinate plane' refer to?

Back

A two-dimensional surface where points are defined by pairs of numerical coordinates.

Front

How do you find the length of a rectangle on a coordinate plane?

Back

Subtract the x-coordinates of the two vertical corners.

Front

How do you find the width of a rectangle on a coordinate plane?

Back

Subtract the y-coordinates of the two horizontal corners.

Front

What is the perimeter of a rectangle with vertices at (1,2), (1,5), (4,2), and (4,5)?

Back

Perimeter = 2 * (3 + 3) = 12 units

Front

True or False: The perimeter of a rectangle is always greater than the sum of its length and width.

Back

False

Front

What is the distance around the outside of a shape called?

Back

Perimeter

Front

If a rectangle has a perimeter of 30 units and a length of 10 units, what is its width?

Back

Width = (30/2) - 10 = 5 units

Front

What is the relationship between the coordinates of a rectangle's corners and its perimeter?

Back

The coordinates help determine the length and width, which are used to calculate the perimeter.
