Area and Perimeter

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is the total distance around the rectangle, calculated by adding the lengths of all four sides or using the formula: P = 2(length + width).

Front

What is the area of a rectangle?

Back

The area of a rectangle is the amount of space inside it, calculated by multiplying the length by the width. Formula: A = length × width.

Front

If a rectangle has a length of 5 feet and a width of 3 feet, what is its area?

Back

15 square feet (A = 5 × 3 = 15).

Front

If a rectangle has a length of 8 feet and a width of 2 feet, what is its perimeter?

Back

20 feet (P = 2(8 + 2) = 20).

Front

What is the formula for finding the perimeter of a square?

Back

The perimeter of a square is calculated using the formula: P = 4 × side length.

Front

What is the area of a square with a side length of 4 feet?

Back

16 square feet (A = 4 × 4 = 16).

Front

What does 'area' refer to in geometry?

Back

Area refers to the amount of space inside a two-dimensional shape.

Front

What does 'perimeter' refer to in geometry?

Back

Perimeter refers to the total distance around a two-dimensional shape.

Front

If a rectangle has a perimeter of 30 feet and a length of 10 feet, what is its width?

Back

5 feet (P = 2(length + width) => 30 = 2(10 + width) => width = 5).

Front

What is the relationship between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around it. They are different concepts.
