Intro Perimeter and Area on the Coordinate Plane

Front

What is the formula for calculating the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width)

Front

What is the formula for calculating the area of a rectangle?

Back

Area = length * width

Front

How do you find the area of a shape plotted on a coordinate plane?

Back

Identify the vertices, calculate the base and height, then use the area formula.

Front

What is the distance formula for two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What does the term 'coordinate plane' refer to?

Back

A two-dimensional surface formed by the intersection of a vertical line (y-axis) and a horizontal line (x-axis).

Front

What is the significance of the coordinates (x, y) in a coordinate plane?

Back

They represent the position of a point relative to the origin (0,0).

Front

How do you calculate the perimeter of a polygon?

Back

Add the lengths of all the sides together.

Front

What is the area of a rectangle with a length of 5 units and a width of 3 units?

Back

Area = 5 * 3 = 15 square units.

Front

If a rectangle has a perimeter of 20 units, what could be its possible dimensions?

Back

Possible dimensions could be (5, 5), (6, 4), (7, 3), etc.

Front

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

Back

Area = 4 * 4 = 16 square units.
