Perimeter and Area

Front

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

Back

The perimeter (P) of a rectangle is calculated using the formula P = 2(length + width).

Front

How do you calculate the area of a rectangle?

Back

The area (A) of a rectangle is calculated using the formula A = length × width.

Front

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

Back

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

Front

How do you calculate the area of a square?

Back

The area (A) of a square is calculated using the formula A = side length × side length.

Front

If a rectangle has a length of 10 meters and a width of 5 meters, what is its perimeter?

Back

The perimeter is 30 meters (P = 2(10 + 5)).

Front

If a square has a perimeter of 40 meters, what is the length of one side?

Back

The length of one side is 10 meters (P = 4 × side length, so side length = 40/4).

Front

What is the relationship between the perimeter and area of a shape?

Back

Perimeter measures the distance around a shape, while area measures the space within a shape. They are related but represent different properties.

Front

How do you convert feet to meters when calculating area or perimeter?

Back

To convert feet to meters, multiply the number of feet by 0.3048.

Front

What is the perimeter of a rectangle with a length of 12 feet and a width of 8 feet?

Back

The perimeter is 40 feet (P = 2(12 + 8)).

Front

If a square has an area of 64 square meters, what is the length of one side?

Back

The length of one side is 8 meters (A = side length × side length, so side length = √64).
