Imagine you want to change the wallpaper
in your lounge. Before you go to buy
the wallpaper you like, you should
find out how much paper you will approximately
need. Have a look at the example below
before trying yourself.
Note: this
activity only gives you an estimate for
how much wallpaper you will need.
It is only an estimate because you
might have to cut out wallpaper for
windows and doors, etc., and because
you might have to waste the remaining
parts of rolls that aren’t long
enough to finish a whole wall’s
length. Let's take a look at an example.
And now – why not try yourself.
Click the button on the right in the
activity below to see if you are calculating correctly!

Imagine that your room has two walls
which are 4.5 metres wide and 2.4
metres high; and two walls which
are 3.2 m wide and 2.4 m high. The
wallpaper that you like is 0.5 m
wide and 9m long. The price for each
role is £7.99.
