Coordinate Plane, Area and Perimeter Review

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

In which quadrant is the point (3, -5) located?

Back

Quadrant IV.

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 cm and a width of 5 cm, what is its perimeter?

Back

Perimeter = 2(10 cm + 5 cm) = 30 cm.

Front

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

Back

Area = length × width.

Front

If a rectangle has a length of 4 cm and a width of 3 cm, what is its area?

Back

Area = 4 cm × 3 cm = 12 sq cm.

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape.

Front

If I wanted to cover my garden with soil, would I be concerned with area or perimeter?

Back

Area.

Front

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

Back

Area = side × side = 5 cm × 5 cm = 25 sq cm.
