Area of a rectangle - Easy

Front

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

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

If a rectangle has a length of 10 units and a width of 4 units, what is its area?

Back

The area is 40 square units (10 × 4 = 40).

Front

What units are used to express the area of a rectangle?

Back

Area is expressed in square units, such as square meters (m²), square centimeters (cm²), or square inches (in²).

Front

How do you find the area of a rectangle when given the perimeter?

Back

To find the area from the perimeter, you need to know either the length or width. The perimeter (P) is given by P = 2(length + width). You can rearrange this to find one dimension if the other is known.

Front

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

Back

The area is 24 cm² (8 × 3 = 24).

Front

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

Back

The length is 10 units (Area = length × width; 50 = length × 5; length = 50/5 = 10).

Front

What is the area of a rectangle with a length of 12 inches and a width of 2 inches?

Back

The area is 24 square inches (12 × 2 = 24).

Front

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

Back

Increasing either the length or width will increase the area, while decreasing either dimension will decrease the area.

Front

What is the area of a rectangle if both the length and width are doubled?

Back

If both dimensions are doubled, the area increases by a factor of four (Area = (2length) × (2width) = 4(length × width)).

Front

If a rectangle has an area of 36 square cm and a width of 6 cm, what is the length?

Back

The length is 6 cm (Area = length × width; 36 = length × 6; length = 36/6 = 6).
