Step-by-step explanation:
You can write the equation of the line by finding the slope between the points and substitute it with a point into the point slope form.

Answer:
88.28
Step-by-step explanation:
applying formula of area of triangle, 1/2 X base X height.
given.= base= 16.9 height=10.4
so keeping value in formula.
1/2 X 16.9 X 10.4
on solving it will be 88.28
Your answer should be 486 inches, you do 9x9 to find the area of one of the faces, and because there is 6 faces, you multiply that answer (81) to get 486
