Let x = the height of the building. So we have, x/2.6 = 42.25/1.51 x = (2.6)(42.25)/1.51 x =72.75 Thus, the building is 72.75 meter tall.
The height of the tree is in direct proportion to the pole and its shadow
It works out as 12 feet and 4 inches in height
A stick is 6/4.5 = 4/3 times its shadow. So the tree is 4/3*25 = 33.3... feet or 33 ft 4 inches tall.
The flagpole is 24 feet tall.Assuming their shadows align exactly, they form similar triangles andh/32 = 6/8Mutiply both sides by 32h = 192/8 = 24

If the building casts a shadow, then the sun is out, and any man who is not standing in theshadow of the building will cast a shadow of his own, no matter how short or tall he may be.(If you had told us the length of the man's shadow, it would have been a completely differentquestion, and we could have had a completely different answer to offer in response.)
40 ft
50 feet
The height of the tree is in direct proportion to the pole and its shadow
It is 90 feet in height
60 inches, or 5 feet.
The lenght of the shadow will be 12.6 ft
Ratio of shadows = 3m:7.5m :: 1:2.5 So, the ratio of the heights (in the same order) is 1:2.5 ie Ht(Pole):Ht(Building) = 40m:Ht(Building) = 1:2.5 So Ht(Building) = 2.5*40m = 100 metres
