Find Perimeter in the Coordinate Plane

Front

What is the definition of perimeter?

Back

The distance around a shape.

Front

How do you find the distance between two points (x1, y1) and (x2, y2) on a coordinate plane?

Back

Use the distance formula: √((x2 - x1)² + (y2 - y1)²).

Front

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

Back

The perimeter is 2(length + width) = 2(5 + 3) = 16 units.

Front

What is the distance between the points (2, 3) and (2, 7)?

Back

The distance is 4 units.

Front

If a rectangle has a perimeter of 20 units and one side is 6 units long, what is the length of the other side?

Back

The other side is 4 units long.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width).

Front

How many units are between the points (1, 1) and (1, 15)?

Back

The distance is 14 units.

Front

What is the distance between the points (3, 4) and (7, 4)?

Back

The distance is 4 units.

Front

If a triangle has sides of lengths 3 units, 4 units, and 5 units, what is its perimeter?

Back

The perimeter is 3 + 4 + 5 = 12 units.

Front

What does it mean if two points have the same x-coordinate?

Back

They are vertically aligned on the coordinate plane.
