I have a question in math. I am supposed to find the area of the shaded region. The rectangle is 7 m long and 4m tall. The entire rectangle is shaded except for two triangles that are on either side of the rectangle. The triangles' base is the height of the rectangle. I am sorry this is so confusing it would be a lot easier to explain if I could draw it.

Given a plane"s equation as 8x+15y-3z-17=0
Write the equation as (x-h) + b(y-k) + c (z-1) = 0 and hence write the normal to the plane and point that passes through the plane.
