Front

What is the definition of perimeter?

Back

Perimeter is the total distance around the outside of a two-dimensional shape, 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: 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. Therefore, 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 circle called?

Back

The perimeter of a circle is called the circumference.

Front

How do you calculate the circumference of a circle?

Back

The circumference of a circle can be calculated using the formula: C = 2πr, where r is the radius.

Front

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

Back

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

Front

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

Back

The perimeter is a measure of the distance around a shape, while the area measures the space contained within it. They are related but represent different properties.

Front

If the perimeter of a polygon is 30 cm and it has 5 equal sides, what is the length of each side?

Back

If the perimeter is 30 cm and there are 5 equal sides, each side length is 30 cm ÷ 5 = 6 cm.

Front

What is the perimeter of a regular hexagon with a side length of 2 cm?

Back

The perimeter of a regular hexagon is calculated as P = 6 × side length. Therefore, P = 6 × 2 cm = 12 cm.
