Perimeter

Front

What is the formula for calculating the perimeter of a polygon?

Back

The perimeter of a polygon is calculated by adding the lengths of all its sides.

Front

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

Back

The perimeter is 28 feet (P = 2(length + width) = 2(10 + 4) = 28).

Front

If a triangle has sides measuring 5 units, 6 units, and 7 units, what is its perimeter?

Back

The perimeter is 18 units (5 + 6 + 7 = 18).

Front

What is the distance around a circle called?

Back

The distance around a circle is called the circumference.

Front

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

Back

Subtract the sum of the known side lengths from the total perimeter to find the missing side length.

Front

What is the perimeter of a square with a side length of 5 inches?

Back

The perimeter is 20 inches (P = 4 * side = 4 * 5 = 20).

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 is the amount of space inside the shape; they are related but measure different properties.

Front

If a rectangle has a perimeter of 50 inches and one side is 15 inches, what is the length of the other side?

Back

The other side is 10 inches (P = 2(length + width) => 50 = 2(15 + width) => width = 10).

Front

What is the perimeter of a triangle with vertices at (0,0), (0,4), and (3,0)?

Back

The perimeter is 12 units (lengths of sides are 4, 3, and 5 units).

Front

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

Back

The perimeter is 36 cm (P = 6 * side = 6 * 6 = 36).
