S = 2(ab + bc + ac)
S = 2(17*8,5 + 8,5*10 + 17*10) = 2(144,5 + 85 + 170) = 799 м2

пересказ умоляю!!!!

Gileno Vieira da Rocha is a Brazilian engineer. He helps to build roads in
the Amazon rainforest. Last year he was in the forest, 300 miles from the
nearest big town. When he finished work one day, he decided to walk back
to the camp, ten kilometres away. His workmates walked along the usual
path. But Gileno decided to take a shortcut. He walked across a field, and
into the jungle. But he got lost. He couldn't see any other people and he
couldn't return to his workmates. He continued to walk through the trees.
He climbed over tree trunks and crawled under bushes. At night he rested
in a tree or on the ground. After a few days he was very hungry, but he
couldn't find any fruit or animals to eat. So he decided to catch bees and
flies for food! Finally, after twelve days, he arrived at a river and started to
walk along it. There were people by the river and they helped him. Gileno
almost died, but he finally arrived home safely. He was a very lucky man!
