This is a problem on a venn diagram in which the problem determines the number of subscribers that are mutually heeding for channel A and channel B. The equation to be followed is
U = U' + A + B + AandB
Substituting,
8500 = 5140 + 2450+1980- AandB
AandB = 1070 subscribers
Area of a trapezoid = a+b+c x h
10 + 5 +12 = 27 x h
27h = 27 x 1.5 = 40.5
