Perimeter of Polygons

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

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

Front

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

Back

Perimeter = 2 × (10 cm + 5 cm) = 30 cm.

Front

What is the perimeter of a square with a side length of 4 meters?

Back

Perimeter = 4 × side length = 4 × 4 m = 16 m.

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is calculated by adding the lengths of all three sides: Perimeter = side1 + side2 + side3.

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 6 m, 8 m, and 10 m?

Back

Perimeter = 6 m + 8 m + 10 m = 24 m.

Front

What is the difference between perimeter and area?

Back

Perimeter measures the distance around a shape, while area measures the space inside a shape.

Front

How do you find the perimeter of a regular polygon?

Back

To find the perimeter of a regular polygon, multiply the length of one side by the number of sides: Perimeter = side length × number of sides.

Front

What is the perimeter of a hexagon with each side measuring 5 cm?

Back

Perimeter = 5 cm × 6 = 30 cm.
