2nd - Saxon Lesson 63 Area and Perimeter Review

Front

What is the PERIMETER?

Back

The perimeter is the total distance around a shape. It is measured in units.

Front

How do you calculate the PERIMETER of a rectangle?

Back

Add the lengths of all four sides or use the formula: P = 2(length + width).

Front

What is the AREA?

Back

The area is the amount of space inside a shape. It is measured in square units.

Front

How do you calculate the AREA of a rectangle?

Back

Multiply the length by the width: A = length × width.

Front

What is a square unit?

Back

A square unit is a unit of measure for area, representing a square that is 1 unit on each side.

Front

If a rectangle has a length of 5 units and a width of 3 units, what is its AREA?

Back

15 square units (A = 5 × 3).

Front

If a rectangle has a length of 4 units and a width of 2 units, what is its PERIMETER?

Back

12 units (P = 2(4 + 2)).

Front

What is the difference between AREA and PERIMETER?

Back

Area measures the space inside a shape, while perimeter measures the distance around it.

Front

If the PERIMETER of a square is 16 units, what is the length of one side?

Back

4 units (P = 4 × side, so side = 16/4).

Front

What is the formula for the PERIMETER of a square?

Back

P = 4 × side.
