-1/240 (Might be wrong though)

Step-by-step explanation:

The first thing we need to do is multiply 1/15 and 1/16 because product means the answer to a multiplication equation.

1/15 times 1/16 = (1*1)/(15*16) = 1/240

Now that we know the product 1/240, we just have to find the opposite, which is -1/240 because you just add a negative sign in opposites( even in negative numbers)

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
