A landscaping company is laying out a triangular flower bed. The height of the triangle is 12ft. What lengths of the base will make the area at least
168ft-sq.
.
Since area of any triangle is (1/2)bh
where
b is the length of the base
h is the height
.
From the above, our equation is:
168 = (1/2)b(12)
168 = b(6)
168/6 = b
28 feet = b
.
So, base has to be 28 feet or greater
