Pleaseee help on these two questions!
1. Use geometry to evaluate integral(with upper bound of 10 and lower bound of 0) of f(x) dx for f(x)= {5, x <=5 and 10-x, x > 5
A. 12.5
B. 25
C. 37.5
D. Cannot be found
2. Use your calculator to evaluate the limit from x equals 0 to 2 of sin(x^2) dx. Give your answer to the nearest integer.
______(fill in the blank)
Thank you in advance for the help. I greatly appreciate it, Thank you!

#1 Really? Draw the graph. You have a square and a triangle. What do you get?
#2 So, use your calculator
You can also verify your result here:

Oobleck, I got 25 for answer one. I got it marked wrong. I guess I did something wrong along the way. Can you please explain to me the process. I don't know where I messed up while working the problem.

The response above is mine. Just figured I'd let you know so that you don't get confused. Thank you!

The square has an area of 25
The triangle to the right has an area of 12.5
Clearly you did not draw the graph, nor read my hint.
