Background
PROBLEM:
In the punalu‘u lo‘i, there is a
taro patch that is a Rectangle.
We need to find out the width
of the rectangle in order to
find the area. we know that
when you split the rectangle
into two triangles the length
of it is 12 and the hypotenuse
is 15. Find the width and area
of the rectangle.
The eighth grade went to
the punalu‘u Lo‘i on october
23, 2009. The punalu‘u lo‘i is
located in the Mokupuni of
O‘ahu and the Moku of
Ko‘olauloa and the Ahupua‘a
of Punalu‘u. This Lo‘i only
deals with the wetland kalo
and while there we helped
clean the weeds out of the lo‘i,
re-mound the lo‘i plants, and
take the shrubs out of the
‘auwai. A wetland LO‘i patch
depends on a constant flow of
cold water, if this was not
present this kind of kalo won‘t
be able to be produced. Going
to the Punalu‘u lo‘i was a
great experience and I hope to
do this again.
