Step-by-step explanation:
The formula of a triangle is A=½bh
Base=6.5
Height=4.8(since the height if the triangle and the width of the rectangle are same)
A=½(6.5)(4.8)
A=½(31.2)

A=15.6
Therefore, the area of the triangle LMN is 15.6

There are 160 total number of students.
Other givens are the following:
40 are honor students
60 are athletes
80 are either honor or athletes
The probability that the chosen student is an athlete:
P = 60/180
P= 0.375
The probability that the chosen student is an honor:
P=40/160
P=0.25
