Area of Rectangles

Front

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

Back

Area = Length x Width

Front

If a rectangle has a length of 5 units and a width of 2 units, what is its area?

Back

10 square units

Front

What are the side lengths of a rectangle if its area is 12 square units and one side is 4 units?

Back

3 units (since Area = Length x Width)

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 x (Length + Width)

Front

What is the perimeter of a rectangle with a length of 6 units and a width of 4 units?

Back

20 units (Perimeter = 2 x (6 + 4))

Front

What is the relationship between the area of a rectangle and its dimensions?

Back

The area is directly proportional to the product of its length and width.

Front

If the area of a rectangle is 50 square cm and the width is 5 cm, what is the length?

Back

10 cm (Length = Area / Width)

Front

What is the area of a rectangle with a length of 8 cm and a width of 3 cm?

Back

24 square cm

Front

How does changing the dimensions of a rectangle affect its area?

Back

Increasing either the length or width increases the area; decreasing either decreases the area.

Front

What is the area of a rectangle with side lengths of 7 units and 2 units?

Back

14 square units
