Front

What is area?

Back

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

Front

How do you find the area of a rectangle?

Back

To find the area of a rectangle, multiply its length (l) by its width (w). Formula: A = l × w.

Front

What does 'l' represent in the area formula A = l × w?

Back

The 'l' in the formula represents the length of the rectangle.

Front

What does 'w' represent in the area formula A = l × w?

Back

The 'w' in the formula represents the width of the rectangle.

Front

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

Back

The area is 12 square centimeters (A = 4 × 3 = 12).

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a number by a sum.

Front

How can you use the distributive property to find the area of a rectangle?

Back

You can break the rectangle into smaller rectangles and add their areas together.

Front

What is the area of a rectangle with a length of 7 units and a width of 5 units?

Back

The area is 35 square units (A = 7 × 5 = 35).

Front

If a rectangle has an area of 20 square centimeters and a width of 4 cm, what is its length?

Back

The length is 5 cm (A = l × w; 20 = l × 4; l = 20/4 = 5).

Front

What are the side lengths of a rectangle with an area of 18 square units?

Back

Possible side lengths could be 6 units and 3 units (6 × 3 = 18).
