Answer:
91 in²
Step-by-step explanation:
Area of tarpezoid = (sum of both bases x height) / 2
A = ((11 + 15) x 7) /2 = 91
80% = 6 in
100%=?
100/x 80/6 (proportional relationship)
then cross multiply
600 = 80x
600/80= 7.5
x=7.5
Surface Area = 2×(5×6 + 5×8 + 6×8) = 236 meters²
Hope this helps! Stay safe, have a good day :D
-- For just a minute, make it an Equality . . . y = x + 2 .
-- Graph the Equality. That graph is a straight line.
-- The INequality says that 'y' is LESS than x+2,
and THAT's everything UNDER the line.
(But not the points on the line itself.)
I would say a time line or bar graph
