The surface area is
A1=7.5*1.5*2=22.5 ft2 top and bottom view
A2=3*1.5*2=9 ft2 laterals view
A3=(7.5*1.5+2.5*1.5)*2=30 ft2 front and rear view
At=22.5+9+30=61.5 ft2
the answer is 61.5 ft2

Answer:
The equation of the line is 
Step-by-step explanation:
Equation of a line:
The equation of line, in point-slope form, is given by:

In which m is the slope and the point is 
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
Through (9,-7)
This means that 
So



Perpendicular to y = 3x + 4
This line has slope 3, so:


Thus
