Review Distance, Area and Perimeter on the Coordinate Plane

Front

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

Back

Area = length × width

Front

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

Back

Perimeter = 2 × (length + width)

Front

What is the distance formula between two points (x1, y1) and (x2, y2) on a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

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

Back

It means the shape's vertices are defined by coordinates (x, y) in a two-dimensional space.

Front

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

Back

Area = 1/2 × base × height

Front

What is the area of a shape with a base of 5 units and a height of 4 units?

Back

Area = 1/2 × 5 × 4 = 10 square units

Front

If a rectangle has a length of 3 units and a width of 2 units, what is its area?

Back

Area = 3 × 2 = 6 square units

Front

What is the perimeter of a rectangle with a length of 4 units and a width of 3 units?

Back

Perimeter = 2 × (4 + 3) = 14 units

Front

What is the area of a square with a side length of 6 units?

Back

Area = 6 × 6 = 36 square units

Front

How do you determine if four points can form a rectangle?

Back

Check if opposite sides are equal and parallel.
