Объяснение:

Пусть x - меньшая сторона, тогда 4x вторая, P = 2(4x+x) = 10x

10x = 60

When Daniel Seddiqui was 26, he travelled around
the USA for a year. He visited all 50 states and
worked for a week in each one. He didn’t use buses
or planes – he travelled by car from job to job.
He earned money for every job he did, but hotels
were too expensive for him. He usually stayed in
his boss’s home, or with one of the other workers.
‘People were very good to me,’ says Daniel. ‘They
looked after me really well.’
But why did Daniel do this? And did he enjoy it? ‘Yes,
I did! I wanted to travel and learn about my country,’
he says. ‘And I wanted to try lots of different jobs.’
Things weren’t always easy for Daniel. In week 7,
he worked as a farmer in Nebraska. ‘The days were
long, and I got really dirty,’ he says. In week 38, he
was a cook in a fish restaurant in Maryland. ‘That
was really hard! Often I didn’t even have time to
get a drink of water.’
Other jobs were fun. He worked at a theme park in
Florida and as a model in North Carolina. He was
a football coach in Alabama. In Alaska, he was
a photographer. ‘That was great.
Alaska is a very beautiful place,’
says Daniel
