What must be true? In your example, we have 4 intersecting lines. g and b are parallel, and f and h are parallel. g and b are perpendicular to f and h. It might look like tic-tac toe for example
......A..B...C...D.. E...1...2...3...4... F...5...6...7...8... G...9..10..11.12. H..13..14.15.16. There are ten rows - A, B, C and D, going downwards - E, F, G and H going across, and 1,6,11 and 16 & 4, 7, 10 and 13 going diagonally.
The area of a trapezoid is equal to (1/2)(B + b)h]. In our case B = 10 ft, b = 8 ft, and h = 5 ft, So A = (1/2)(B + b)h = (1/2)(10 + 8)(5) = 45 ft^2
A = bhThis actually means A = b multiplied by h.A = 8 multiplied by 4A = 32
