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 formula for the perimeter of a square?

Back

The perimeter of a square is calculated using the formula: P = 4 × side length.

Front

How do you find the perimeter of a triangle?

Back

To find the perimeter of a triangle, add the lengths of all three sides: P = side1 + side2 + side3.

Front

What is the perimeter of a heptagon with equal sides of length 8 m?

Back

The perimeter of a heptagon with equal sides is calculated as P = 7 × side length. For sides of 8 m, P = 7 × 8 = 56 m.

Front

What is the perimeter of a shape with sides measuring 5 m, 7 m, and 8 m?

Back

The perimeter is calculated by adding the lengths of the sides: P = 5 m + 7 m + 8 m = 20 m.

Front

What is the perimeter of a triangle with sides measuring 3 ft, 4 ft, and 5 ft?

Back

The perimeter is P = 3 ft + 4 ft + 5 ft = 12 ft.

Front

How do you calculate the perimeter of a polygon with unequal sides?

Back

Add the lengths of all the sides together to find the perimeter.

Front

What is the perimeter of a shape with a length of 10 cm and a width of 5 cm?

Back

The perimeter is calculated as P = 2(length + width) = 2(10 cm + 5 cm) = 30 cm.

Front

What is the relationship between perimeter and area?

Back

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