Answer:

A = 2 13/32

Explanation:

The formula for the area of a triangle of base b and height h is

A = (1/2)(base)(height) = (1/2) · b · h

Here, the area is:

A = 2 13/32

A = (1/2)(1 3/4)(2.75)

Rewrite 1 3/4 as the improper fraction 7/4, and 2.75 as the improper fraction 11/4.

Then:

A = (1/2)(7/4)(11/4), which comes out to A = 77/32, or 2 13/32.
