Do you know what would be a suitable unit to measure the area of a classroom?

# Perimeter and Area (Year 4)

In KS2 Maths, you'll learn cool stuff about shapes! In Year Four, we'll figure out how long the sides of squares and rectangles are, and what goes around them – that's called the perimeter. We'll also learn the area, which is like the space inside the shape. We use special units like mm2, cm2, or m2. We'll even make good guesses about how much space a shape takes up.

Imagine a rectangle – we can find its area by multiplying how long it is by how short it is! The answer will be in square mm, cm, or m. So hey, let's take a fun quiz for 8-9 year olds and show off your area and perimeter skills!

1.
What is useful to work out the area of a small 2D shape?
Tracing paper
Measuring jug
Metre stick
Squared paper
Squared paper helps to work out the area of irregular shapes too
2.
Which would be a good estimate of the area of a small notebook?
1,000cm2
5cm2
26cm2
500cm2
This would be a very small notebook measuring 4cm x 6.5cm
3.
Which would be a suitable unit to measure the area of a classroom?
Square metres
Square millimetres
Square centimetres
Square kilograms
Millimetres and centimetres would be way too small and kilograms measure weight!
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.
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
6.
How is square centimetre usually written?
Cm sq
Sq cm
cm2
2cm
Cubed cm are written as cm3
7.
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
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
9.
Which is a good estimate of the perimeter of a mobile 'phone?
100cm
34cm
2m
25mm
100cm = 1m That's way too big for a 'phone!
10.
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
