Front

What is Perimeter?

Back

Perimeter is the total distance around a shape. For rectangles, it is calculated as length + length + width + width.

Front

How do you calculate the Perimeter of a square?

Back

The perimeter of a square is calculated as length x 4, since all sides are equal.

Front

What is Area?

Front

What is the Perimeter of a rectangle with a length of 5 cm and a width of 3 cm?

Back

Perimeter = 5 cm + 5 cm + 3 cm + 3 cm = 16 cm.

Front

What units are used to measure Area?

Back

Area is measured in square units, such as square centimeters (cm²) or square feet (ft²).

What is the Perimeter of a rectangle with a length of 10 yards and a width of 1 yard?

Back

Perimeter = 10 yards + 10 yards + 1 yard + 1 yard = 22 yards.

Front

If a rectangle has an Area of 12 square units and a width of 3 units, what is its length?

Back

Length = Area ÷ Width = 12 square units ÷ 3 units = 4 units.
