Answer:

15 units²

Step-by-step explanation:

Hi there!

A=\displaystyle\frac{1}{2} bh where <em>b</em> is the base and <em>h</em> is the height

Plug in the base (7.5) and height (4):

A=\displaystyle\frac{1}{2} (7.5)(4)\\\\A=\displaystyle\frac{1}{2} (30)\\\\A=15

Therefore, the area of the triangle is 15 units².
