-8
Step-by-step explanation:
Perpendicular means negative reciprocal of the slope.
Negative reciprocal of 1/8 is -8.

<u>Examples</u>:
(-1)(-1) = 1
(-1)(-1)(-1) = -1
(-1)/(-1) = 1
(-1)(-1)/(-1) = -1

Answer:
54 or 57 (read explanation below)
Step-by-step explanation:
There is a mistake in the problem.
The bottom base has length 10 not 11.
Using the correct length of 10, the area is:
A = (1/2)h(b1 + b2)
A = (1/2)(6)(10 + 8)
A = 3(18)
A = 58
Using the incorrect length of 11, the area is:
A = (1/2)h(b1 + b2)
A = (1/2)(6)(11 + 8)
A = 3(19)
A = 57
