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

He would gain by choosing air travel if, and only if, he values his time at more than $5 per hour.
Step-by-step explanation:
The problem states that:

So, dividing the extra cost by the number of hours saved:
He would gain by choosing air travel if, and only if, he values his time at more than $5 per hour.
