Which of these options are linear?

B table

Step-by-step explanation:

The B table is a linear table because with each x value, the y value is moving steadily with addition/subtraction. Table A is moving steadily with multiplication.

The lateral area is the area of everything but the base.  A shortcut formula for this area is Ph.  (where P is the perimeter of the base and h is the height of the prism).

So the lateral area is (3+9+9.49)x37 = 795.13 m^2  or 795 m^2

The surface area is the lateral area plus the area of the 2 bases.  The base is a triangle.  (area = 1/2 bh) 

Since there are two identical bases, the total area of the base is just 3x9 = 27

So the surface area is 795.13 + 27 = 822.13 m^2 or 822 m^2.
