We want to find the probability that a student uses the Internet, given that he or she is in eighth grade. Mathematically:
P(Internet | eighth grade) = P(Internet ∩ eighth grade)/P(eighth grade)
P(Internet | eighth grade) = (8/28)/(13/28) = 8/13 = 0.62

Split the shape into smaller shapes, (see attachment)
find the area of the split shapes. So first find the area of the triangles
A = 1/2bh
A = 1/2*2*3
A = 1/2*6
A = 3
so that is the area of one triangle. the area of the other is
A = 1/2*4*3
A = 1/2 * 12
A = 6
now find the area of the rectangle
A = l*w
A = 9*3
A = 27
add them all together
27 + 6+ 3 = 36
the area of the total figure is 36
