I assume you mean the triangle that the ladder makes with the ground and the wall. Area = (1/2)ab d(Area)/dt = (1/2)a db/dt + (1/2)b da/dt so when a= 5, b=12 , db/dt = 6, da/dt = -72/5 d(Area)/dt = (1/2)(5)(6) +(1/2)(12)(-72/5) = 15 - 86.4 = -71.4

Well, I bet it turns out to be a square but anyway: A = b c where b is breadth and c is length 2 b + 2 c = 800 so b + c = 400 c = (400 - b) so A = b * (400-b) A = 400 b - b^2 b^2 - 400 b + A = 0 where is the vertex of this parabola (I assume you do not do calculus) b^2 - 400 b...

xy=384 so, y = 384/x f = 2x+3y = 2x + 1152/x df/dx = 2 - 1152/x^2 min f is when df/dx=0, at x=24 So, the field is 24x16 f = 48+48=96 as usual in these problems, the fencing is divided equally among lengths and widths.

Calculus - Definite Intergrals
the equilibrium price is where supply equals demand. 71 - 1/10 x = 35 + 1/20 x x = 240 Pmax (the y-intercept of D) is 710 Consumer surplus is thus ∫[240,710] D(x) dx and just take it from there. Similarly for producer surplus.
