Area of Squares and Rectangles

Front

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

Back

The area of a square is calculated using the formula: Area = side × side (A = s²), where 's' is the length of one side.

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 (A = l × w).

Front

If a square has a side length of 5 units, what is its area?

Back

The area of the square is 25 square units (5 × 5 = 25).

Front

If a rectangle has a length of 8 cm and a width of 5 cm, what is its area?

Back

The area of the rectangle is 40 square centimeters (8 × 5 = 40).

Front

What is the area of a square with an area of 81 sq. m?

Back

The side length of the square is 9 meters, since the area is calculated as A = s² (s = √81 = 9).

Front

How do you find the area of shaded regions in a composite figure?

Back

To find the area of shaded regions, calculate the total area of the figure and subtract the area of the unshaded parts.

Front

What is the area of a rectangle with a length of 10 cm and a width of 4 cm?

Back

The area of the rectangle is 40 square centimeters (10 × 4 = 40).

Front

If a square has an area of 36 sq. m, what is the length of one side?

Back

The length of one side is 6 meters, since s = √36.

Front

What is the relationship between the side length of a square and its area?

Back

The area of a square increases with the square of its side length; doubling the side length increases the area by a factor of four.

Front

How can you determine the area of a figure made up of multiple squares and rectangles?

Back

Calculate the area of each individual square and rectangle, then sum these areas to find the total area.
