Let the length of the wall be l = 26ft, the distance of the lower end of the ladder from the wall be x and the height of the top of the ladder from the ground be y, then
l = sqrt(x^2 + y^2) = 26
x^2 + y^2 = 26^2 = 676
y^2 = 676 - x^2
y = sqrt(676 - x^2)
dy/dt = -2x dx/dt / 2sqrt(676 - x^2) = -2(10)(5) / 2sqrt(676 - (10)^2) = -100 / 48 = -2.083 ft/sec.
Area of triangle = 1/2 (base) (height)
base = 20.3 cm and height = 6.2 cm
Plug in
A = 1/2 (20.3)(6.2)
A = 62.93
Answer
62.93 cm^2
