(area of blue triangle) + (area of red rectangle) + (area of green rectangle) = 10,800
Area of triangle = (base)(height)/2
So, we get: (x)(96)/2 + 4x + (4)(100) = 10,800
Simplify: 48x + 4x + 400 = 10,800
Simplify: 52x + 400 = 10,800
Subtract 400 from both sides to get: 52x = 10,400
Solve: x = 10,400/52 = 200
Answer: A
Cheers,
Brent

total area of the ∆ plaza = 100 -4 * x/2 = 48x
and the area of the rectangular part ; (x+4)*(4)+(96)*4 = 4x+400
total area ; 52x+400= 10800
x= 200
IMO A
