The shape in the image is a right triangle, with a height of 2.1 inches and a base of 6.8 inches.

The formula for the area of a triangle is:

$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$

Substituting the given values:

$\text{Area} = \frac{1}{2} \times 6.8 \, \text{in} \times 2.1 \, \text{in}$

Let me calculate that for you.The area of the triangle is $7.14$ square inches.
