Answer:
88
Explanation:
area of a triangle: 1/2 x length x height
1/2 x 16 x 11
= 88
the area is 88cm^2
I haven't seen a question laid out like this before though so 'square units' might mean you have to do something else to 88cm^2. I'd assume it's just 88 square units personally but feel free to check me on that. :)
