Perimeter

Front

What is perimeter?

Back

Perimeter is the total distance around the outside of a shape. It is calculated by adding the lengths of all the sides.

Front

How do you calculate the perimeter of a rectangle?

Back

To calculate the perimeter of a rectangle, use the formula: P = 2(length + width).

Front

What is the perimeter of a square with a side length of 5 cm?

Back

The perimeter of a square is calculated as P = 4 × side length. So, P = 4 × 5 cm = 20 cm.

Front

If a triangle has sides measuring 3 cm, 4 cm, and 5 cm, what is its perimeter?

Back

The perimeter of the triangle is the sum of its sides: 3 cm + 4 cm + 5 cm = 12 cm.

Front

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

Back

Using the formula P = 2(length + width), the perimeter is P = 2(10 cm + 4 cm) = 28 cm.

Front

If a shape has a perimeter of 30 cm and one side is 10 cm, what is the total length of the other sides?

Back

The total length of the other sides is 30 cm - 10 cm = 20 cm.

Front

What is the perimeter of a figure with sides measuring 2 units, 3 units, and 5 units?

Back

The perimeter is the sum of the sides: 2 units + 3 units + 5 units = 10 units.

Front

How do you find the missing side length if the perimeter of a rectangle is known?

Back

Subtract the sum of the known sides from the total perimeter to find the missing side length.

Front

What is the perimeter of a square with a side length of 8 feet?

Back

The perimeter is P = 4 × 8 feet = 32 feet.

Front

If a rectangle has a perimeter of 50 cm and one side is 15 cm, what is the other side?

Back

Using the formula P = 2(length + width), the other side is (50 cm / 2) - 15 cm = 10 cm.
