Answer: 282.15cm. ^2(squared)
Explanation:
Hey!
So for this problem we first need our formula.
For a right triangle, it would be:
A=1/2bh
B=base (bottom line)
H= height (middle line)
Since that’s is technically two right triangle to make 1, you could just multiple your final result by 2 or just do base times height.
We’re going to do 1/2bh x 2 so I can show you both ways.
Our base is 27, so we are going to split that in half into 13.5.
We already have our height so now all we do is multiply.
13.5 x 20.9=282.15
Now we divide by 2 (if you only wanted one half of the triangle) and we would get 141.07.
Since you need the whole triangle area, your final answer would be 282.15cm. ^2(squared)
