Coordinate Plane Area

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair of numbers (x, y).

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

What is perimeter?

Back

Perimeter is the total distance around a two-dimensional shape, calculated by adding the lengths of all its sides.

Front

How do you find the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using the formula: Perimeter = 2(length + width).

If a rectangle has a perimeter of 72 feet, what is the length if the width is 12 feet?

Back

Using the formula: 72 = 2(length + 12), the length is 24 feet.

What is the area of a shape?

Back

The area of a shape is the amount of space it occupies, measured in square units.
