Area and perimeter on the coordinate plane

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

What is the area of a quadrilateral on a coordinate plane?

Back

The area can be calculated using the shoelace formula or by dividing it into triangles.

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

If a rectangle has an area of 36 square meters and a length of 3 meters, what is the width?

Back

Width = Area / Length = 36 / 3 = 12 meters.

Front

What is the area of a rectangle with a length of 7 units and a width of 4 units?

Back

Area = 7 × 4 = 28 square units.

Front

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

Back

Area = 1/2 × base × height.

Front

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

Back

Perimeter = 2 × (5 + 3) = 16 units.

Front

What is the area of a square with a side length of 5 units?

Back

Area = side × side = 5 × 5 = 25 square units.

Front

How do you determine the coordinates of the vertices of a rectangle given two opposite corners?

Back

Use the x and y coordinates of the corners to find the other two vertices.
