Perimeter and Area Posttest 24-25

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is the total distance around it, calculated by adding the lengths of all four sides or using the formula: P = 2(length + width).

Front

How do you calculate the area of a rectangle?

Back

To find the area of a rectangle, multiply the length by the width. The formula is: Area = length × width.

Front

What is the formula for the area of a square?

Back

The area of a square is calculated by squaring the length of one of its sides. The formula is: Area = side × side.

Front

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

Back

The perimeter is 16 units, calculated as P = 2(5 + 3) = 16.

Front

If a square has a side length of 6 cm, what is its area?

Back

The area is 36 square cm, calculated as Area = 6 cm × 6 cm.

Front

If the perimeter of a rectangle is 20 units and the width is 4 units, what is the length?

Back

The length is 6 units, calculated as Length = (Perimeter/2) - Width = (20/2) - 4.

Front

What is the perimeter of a square with a side length of 4 cm?

Back

The perimeter is 16 cm, calculated as P = 4 × side = 4 × 4.

Front

How do you find the missing side of a rectangle if you know the perimeter and one side?

Back

Use the formula: Length = (Perimeter/2) - Width.
