It is known that the height of ladder ABCD is h. The two diagonals form angles of 30 degrees and 45 degrees respectively with the bottom to calculate the area of ladder

It is known that the height of ladder ABCD is h. The two diagonals form angles of 30 degrees and 45 degrees respectively with the bottom to calculate the area of ladder

Trapezoidal ABCD, as AE ⊥ DC, DF ⊥ DC, < BDC = 30 °, ACD = 45 °,
BF/DF=tan30°,DF=BF/tan30°=√3h,
AE/CE=tan45°,CE=AE/tan45°=h,
CE+DF=DE+EF+EF+CF=CD+AB=h+√3h
The area of trapezoid ABCD = (CD + AB) * H / 2
=(h+√3h)*h/2
=(√3+1)h^2/2
