Front

What is the definition of perimeter?

Back

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 a rectangle?

Back

Perimeter (P) = 2(length + width).

Front

What is the formula for the area of a rectangle?

Back

Area (A) = length × width.
