Front

What is the perimeter of a polygon?

Back

The perimeter of a polygon is the total distance around the polygon, calculated by adding the lengths of all its sides.

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

What is the formula for the perimeter of a square?

Back

Perimeter = 4 × side length.

Front

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

Back

Perimeter = 3 cm + 4 cm + 5 cm = 12 cm.

Front

What is the perimeter of a polygon with sides measuring 5 cm, 7 cm, and 10 cm?

Back

Perimeter = 5 cm + 7 cm + 10 cm = 22 cm.

Front

If a square has a perimeter of 20 cm, what is the length of each side?

Back

Each side = 20 cm / 4 = 5 cm.

Front

What is the perimeter of a regular hexagon with each side measuring 6 cm?

Back

Perimeter = 6 cm × 6 = 36 cm.

Front

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

Back

Subtract the sum of the known sides from the total perimeter.

Front

What is the perimeter of a polygon with 4 sides measuring 2 cm, 3 cm, 4 cm, and 5 cm?

Back

Perimeter = 2 cm + 3 cm + 4 cm + 5 cm = 14 cm.

Front

If a rectangle has a length of 10 cm and a width of 4 cm, what is its perimeter?

Back

Perimeter = 2 × (10 cm + 4 cm) = 28 cm.
