Answer:
15 units²
Step-by-step explanation:
Hi there!
[tex]A=\displaystyle\frac{1}{2} bh[/tex] where b is the base and h is the height
Plug in the base (7.5) and height (4):
[tex]A=\displaystyle\frac{1}{2} (7.5)(4)\\\\A=\displaystyle\frac{1}{2} (30)\\\\A=15[/tex]
Therefore, the area of the triangle is 15 units².
I hope this helps!
