Answer:
total= 98
Step-by-step explanation:
so the way to do this is to find the total surface area of the white bench and then subtract the interfacing portion for the support, and then total surface area of support and also subract the area of the interface with the white as well as the ground
bench top area
area of long side *number of sides + area of end *number of ends
(9*2)*4+(2*2)*2= 72+8=80
interface area is area of long side of red portion
5*2=10
support area is same as bench top for rationale
(5*2)*4+(2*2)=40+8=44
total surface area = area of white + area of red - 2* interface area - bottom of red that interfaces with the ground
total = 80+48-2*10-(5*2)
total = 128-20-10
total= 98
