Front

What is the definition of perimeter?

Back

Perimeter is the total distance around the outside of a polygon or shape, calculated by adding the lengths of all its sides.

Front

How do you calculate the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using 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 using the formula P = 4 × side length. For a side length of 5 cm, P = 4 × 5 = 20 cm.

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: P = side1 + side2 + side3.

Front

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

Back

The perimeter is calculated by adding the lengths of the sides: P = 3 + 4 + 5 = 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 is calculated using the formula C = 2πr, where r is the radius.

Front

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

Back

The perimeter of a regular hexagon is calculated using the formula P = 6 × side length. For a side length of 6 cm, P = 6 × 6 = 36 cm.

Front

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

Back

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

Front

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

Back

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