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 are the coordinates of a point in the first quadrant?

Back

Both x and y coordinates are positive.

Front

What are the coordinates of a point in the second quadrant?

Back

x coordinate is negative, y coordinate is positive.

Front

What are the coordinates of a point in the third quadrant?

Back

Both x and y coordinates are negative.

Front

What are the coordinates of a point in the fourth quadrant?

Back

x coordinate is positive, y coordinate is negative.

Front

How do you plot the point (3, 2) on a coordinate plane?

Back

Move 3 units right (x-axis) and 2 units up (y-axis).

Front

What is the area of a rectangle with a length of 5 units and a width of 4 units?

Back

Area = 5 × 4 = 20 square units.

Front

What is the perimeter of a rectangle with a length of 6 units and a width of 3 units?

Back

Perimeter = 2 × (6 + 3) = 18 units.

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.
