**MathMate**, Sunday, December 13, 2009 at 7:04pmArea of triangle = (1/2)base*height

here we need to convert the mixed numbers (i.e. sum of number and fractions) to improper fractions (numerator is greater than the denominator) to facilitate the eventual multiplication:

base = 3 5/8 in. = (8*3+5)/8" = 29/8"

height = 2 1/2 in. =(2*2+1)/2" = 5/2"

Now calculate the area

A = (1/2)*(29/8)*(5/2)

=145/32 sq.in.

Convert the improper fraction into a mixed number and make your choice of the answers.
