Explanation / Answer

a) h/d = H-h/ (D+d).... and solve for H, the vertical height of

builiding.

Recall that h is .0.32m, D is 95m, and d is 0 .50m

So:

0.32/0.50 = H-0.32/(95+0.50)

=> 0.64 = H-0.32/95.5

=> H = 61m

b) increases. decreasing d which is .50m, will increase the ratio of D/d.... so answer in part a will also increase
