Front

What is the definition of Area?

Back

Area is the amount of space inside a shape, measured in square units.

Front

What is the formula to calculate the Area of a rectangle?

Back

Area = Length × Width.

Front

What is the definition of Perimeter?

Back

Perimeter is the total distance around the outside of a shape.

Front

What is the formula to calculate the Perimeter of a rectangle?

Back

Perimeter = 2 × (Length + Width).

Front

If a rectangle has a length of 5 units and a width of 4 units, what is its Area?

Back

Area = 5 × 4 = 20 square units.

Front

If a rectangle has a length of 5 units and a width of 4 units, what is its Perimeter?

Back

Perimeter = 2 × (5 + 4) = 18 units.

Front

What units are used to measure Area?

Back

Area is measured in square units, such as square meters (m²) or square feet (ft²).

Front

What units are used to measure Perimeter?

Back

Perimeter is measured in linear units, such as meters (m) or feet (ft).

Front

How does changing the length of a rectangle affect its Area?

Back

Increasing the length increases the Area, while decreasing the length decreases the Area.

Front

How does changing the width of a rectangle affect its Perimeter?

Back

Changing the width affects the Perimeter; increasing the width increases the Perimeter.
