Answer:B
Step-by-step explanation:
A is wrong because it's less than the 450.
D is wrong because 2 inches would equal 900. So, you're down to B or C. Multiply 450×1.4= 630. 450×1.5= 675. 630 is closer to 635, therefore it is the answer.
First, you multiply 9 x 13 x 10 = 1170 which is the area of the whole triangle
Then, divide that, 1170, by 2 which equals 885.
So your answer (which im pretty sure is correct) 885
