given focal length of the lens, f = 87.7 mm = 8.77 cm
a. slide distance from the lens, u = -90.782 mm = -9.0782 cm
screen distance from lens = v
so from thin lens formula
1/v - 1/u = 1/f
1/v = 1/8.77 - 1/9.0782
v = 258.3251 cm from the lens
b. width of slide, w = 24 mm
magnification , m = -v/u = 28.45554
hence
width of the image = mw = 682.93316 mm
c. height of slide, l = 36 mm
height of image = l*m = 1024.39974 mm
