Длина изгороди 30*4 = 120. Это же квадрат, а у квадрата 4 стороны.

Раскройте скобки и вставьте слова, подходящие грамматически
и лексически.
For almost
every __1__ (person) there will be a time in their life when they decide that
they want to volunteer. There could be ___2_____ (number) reasons why you want
to start doing volunteering work – from __3___ (retire) through to plain old
fashioned good will. Different people may find different arguments in favour of
doing this kind of work or even service, if I can put it this way. But how do
you get into the world of _4____ (volunteer)?
First of
all you need to make the time to volunteer and before you can start approaching
___5___
(organize) and enquiring about volunteering opportunities you need to first
figure out how much of your time you can dedicate to volunteering. If you are
working then ask your employer if you can have consistent __6____ (week) days
off, so you can then have regular time to volunteer each week. When you can
promise a set amount of time to an organization then they are much more likely
to offer you a volunteering position. So think twice whether you can allocate
enough time to this work before you start, otherwise it can be very
disappointing for both sides.
Next it is
time to think about why you want to volunteer. This one may sound obvious, but
have a good long think about the reasons why you are volunteering. Is it because
you’re __7____
(passion)
about helping others? Is it because you want to meet and spend time with new
people? Or is it because you want to gain further experience and ___8____
(qualify)? Knowing your motive can help you decide which organizations and roles
are __9__ (good) suited to your wants. Mind there are more opportunities for
volunteering that you might know about or imagine.
The next
step is to find an organization to volunteer with. You can volunteer at a local
__10__ (home) shelter or at a charity shop. Maybe you like working with
children, in which case the local youth center would be an ideal place to start
with. Perhaps animals are more your thing, so you could ask a local animal
shelter if they need a hand. As it was _11_____ (mention) before, there are
plenty of places you could volunteer to work with. Simply do your research,
find the place that suits you and get in touch. Many organizations don’t
advertise that they’re looking for volunteers, so it may be up to you to make
the _12____ (one) move and contact them.-
