L.O. Solving mathematical puzzles and problems
Farmer Brown finds some extra fencing. He builds a
rectangular enclosure like this……
4 + 20 + 4 + 20
His daughter, Nita, builds another enclosure with the
perimeter of….
7 + 17 + 7 + 17
How much fencing have they used ?
Mr Brown says to Nita, “That’s not right. Your goat
has got more grass to eat than mine.”
Nita replies,” That can’t be true. Mine can’t have
more grass because we both used the same amount
of fencing.”
Have both goats got
the same amount of
grass?
Mr Brown and Nita need to find out how to make the
rectangle of fencing using 48m so that each of their
goats gets the greatest amount of grass possible.
Can you help them?
