Front

What is the perimeter of a shape?

Back

The perimeter is the total distance around the outside of a shape, calculated by adding the lengths of all its sides.

Front

How do you calculate the perimeter of an irregular shape?

Back

To calculate the perimeter of an irregular shape, measure the length of each side and then add those lengths together.

Front

If a shape has sides measuring 3 units, 4 units, and 5 units, what is its perimeter?

Back

The perimeter is 3 + 4 + 5 = 12 units.

Front

What is the perimeter of a rectangle with a length of 5 units and a width of 3 units?

Back

The perimeter is 2(length + width) = 2(5 + 3) = 16 units.

Front

What is the formula for the perimeter of a square?

Back
