When measuring a 2D shape, like a square or a rectangle, it is useful to know what the perimeter and area of a shape are. The perimeter is the total distance around the outside of a two-dimensional shape. Area is the amount of space covered by the shape's surface. To work out the area of a rectangle multiply the length of its longest side by the length of its shortest side. This will give you an answer in square mm, cm or m (mm^{2} cm^{2} or m^{2}).

1.

What is useful to work out the area of a small 2D shape?

Tracing paper

Measuring jug

Meter stick

Squared paper

Squared paper helps to work out the area of irregular shapes too

2.

A square has a perimeter of 32cm. How long are the sides?

4cm

8cm

10cm

16cm

As a square has four equal sides, we divide by 4 to get the answer

3.

Which is a good estimate of the perimeter of a cell 'phone?

100cm

34cm

2m

25mm

100cm = 1m That's way too big for a 'phone!

4.

What is area?

The distance around the edge of a 2D shape

The distance across a 2D shape

The size of the surface of a 2D shape

The distance around the edge of a 3D shape

Area is measured in square mm cm m or km

5.

Which would be a suitable unit to measure the area of a classroom?

Square meters

Square millimeters

Square centimeters

Square kilograms

Millimeters and centimeters would be way too small and kilograms measure weight!

6.

How is square centimeter usually written?

Cm sq

Sq cm

cm^{2}

Cubed cm are written as cm^{3}

7.

What is a perimeter?

The distance around the edge of a shape

The distance across a shape

The size of the surface of a 2D shape

The size of the surface of a 3D shape

To calculate the perimeter of a 2D shape, add together the length of each side

8.

What is the perimeter of a rectangle 5cm x 9cm?

14cm

20cm

28cm

45cm

A rectangle has two sides of equal length and two more side with equal length. So the answer is:

(2 x 5) + (2 x 9) which is

10 + 18 = 28

(2 x 5) + (2 x 9) which is

10 + 18 = 28

9.

What is the perimeter of a 6cm square?

6cm

12cm

18cm

24cm

A square has four equal sides, therefore the perimeter will be 4 x 6 = 24

10.

Which would be a good estimate of the area of a small notebook?

1,000cm^{2}

5cm^{2}

26cm^{2}

500cm^{2}

This would be a very small notebook measuring 4cm x 6.5cm
