Finding Perimeters

Front

What is the perimeter of a square?

Back

The perimeter of a square is the total distance around it, calculated as 4 times the length of one side.

Front

If a square has a perimeter of 20 cm, what is the length of one side?

Back

5 cm (Perimeter = 4 x side length, so side length = Perimeter / 4 = 20 cm / 4 = 5 cm).

Front

What is the formula to find the perimeter of a rectangle?

Back

Perimeter = 2 x (length + width).

Front

If a rectangle has a length of 10 m and a width of 5 m, what is its perimeter?

Back

30 m (Perimeter = 2 x (10 m + 5 m) = 2 x 15 m = 30 m).

Front

What is the perimeter of a rectangle with a width of 4 m and a length of 13 m?

Back

34 m (Perimeter = 2 x (4 m + 13 m) = 2 x 17 m = 34 m).

Front

How do you check if a given perimeter is correct?

Back

You can check by calculating the perimeter using the dimensions of the shape and comparing it to the given value.

Front

What is the perimeter of a rectangle with a width of 8 cm and a length of 2 cm?

Back

20 cm (Perimeter = 2 x (8 cm + 2 cm) = 2 x 10 cm = 20 cm).

Front

If a shape has a perimeter of 12 feet, what could be the dimensions of the shape?

Back

Possible dimensions could be 3 feet by 3 feet for a square, or 2 feet by 4 feet for a rectangle.

Front

What does it mean if a student says the perimeter of a shape is incorrect?

Back

It means that the calculated perimeter does not match the actual distance around the shape based on its dimensions.

Front

What is the perimeter of a square with each side measuring 6 cm?

Back

24 cm (Perimeter = 4 x 6 cm = 24 cm).
