Perimeter of Rectangles on Coordinate Plane

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is the total distance around the rectangle, calculated as P = 2(length + width).

Front

How do you calculate the perimeter of a rectangle on a coordinate plane?

Back

Identify the coordinates of the rectangle's corners, find the length and width using the distance between the x and y coordinates, then use P = 2(length + width).

Front

What are the coordinates of a point in the coordinate plane?

Back

Coordinates are written as an ordered pair (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What is the X-axis?

Back

The X-axis is the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What is the Y-axis?

Back

The Y-axis is the vertical line on a coordinate plane where the x-coordinate is zero.

Front

How many quadrants are there in the coordinate plane?

Back

There are 4 quadrants in the coordinate plane.

Front

What is the formula for finding the perimeter of a rectangle with length 10 units and width 4 units?

Back

P = 2(10 + 4) = 28 units.

Front

If a rectangle has vertices at (1,2), (1,5), (4,2), and (4,5), what is its perimeter?

Back

P = 2((4-1) + (5-2)) = 2(3 + 3) = 12 units.

Front

What does it mean for a rectangle to be on the coordinate plane?

Back

It means that the corners of the rectangle are defined by specific coordinates (x, y) on the grid.

Front

What is the length of a rectangle if its coordinates are (2,3) and (2,7)?

Back

The length is the difference in the y-coordinates: 7 - 3 = 4 units.
