Perimeter of Rectangles on Coordinate Plane

Front

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

Back

Perimeter = 2 * (length + width)

Front

If a rectangle has a length of 10 units and a width of 5 units, what is its perimeter?

Back

Perimeter = 2 * (10 + 5) = 30 units

Front

What does the term 'coordinate plane' refer to?

Back

A two-dimensional surface where points are defined by pairs of numbers (x, y).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, written as (x, y).

Front

What is the origin in a coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

How do you find the area of a rectangle?

Back

Area = length * width.

Front

If a rectangle has an area of 24 square units and a width of 4 units, what is its length?

Back

Length = Area / Width = 24 / 4 = 6 units.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, always positive.

Front

What is the absolute value of -57?

Back

57

Front

How do you plot the point (3, 4) on a coordinate plane?

Back

Move 3 units right on the x-axis and 4 units up on the y-axis.
