triangle properties
The area of a triangle = 1/2 base x height
The area of a triangle is half the area of the bounding
rectangle you could draw around it. It’s usually written and
found using the formula “half of base times height.” The
base is any one of the sides, and the height is the length of
the altitude you could draw on that side to the opposite vertex
(corner).
So does this mean
we’re ready to
choose a venue?
The area of
the bounding
rectangle would
be base x height.
The height is
the length of
the altitude
on the base.
You might need to
use the Pythagorean
Theorem to find this.

Don’t forget that you’ve got fencing costs.
Assume it’s a sellout and that each person
needs 2 square meters of area.
