its A.
Step-by-step explanation:
its B
3•-13/8 is -4.875 or or -4 7/8
draw a rectangle around it:
the widest part is from about -3 to 2 which is 5 units wide
height is from 3 to -4, which is 7 units
5*7 = 35
the top and bottom are angled so you can subtract a little for that
so I would estimate around 32 square units
Subtract them left to right
