B is the answer 1/2. $$$$$$$
Answer:
Area of resulting triangle will be 900
.
Step-by-step explanation:
When sides of any polygon if scaled by a factor of k
then area is scaled by
According to the above statement
therefore here in the question since area of original triangle was 36
and both base and height are scaled by a factor of 5.
therefore area of scaled triangle will be
times of the original
that is 25 x 36 which gives 900 
So area of resulting triangle will be 900 
The answer would be 10 because 9+-5=4+-1=5+5=10
