Step-by-step explanation:
Hope this helps!
Answer:
solution given:
For triangle
side1=9ft
side2=10ft
base[b]=11ft
height[h]=7.7ft
and for rectangle
length [l]=3ft
wide [w]=9ft
Now
total surface area=lateral surface area +2curved surface area
=perimeter of triangle×length +2area of triangle
=(9+10+11)×3+2×1/2×2(½×b*h)
=90+11×7.7
=174.7
=175ft²is a required answer.

Answer:
A) 16
Step-by-step explanation:
The ratio of long-side to short-side is the same for all of these similar triangles, so we have ...
e/8 = 8/4
e = 8(8/4) = 8(2) = 16
The value of e is 16.
Its 4 because its the gcf not the lcd
