The shadow:object ratio is 1:1 so the tree is 63 feet high.
You need more information to solve this problem. The length of a shadow depends on the angle of the sun which depends on the time of day.
1.8 meters. The ratio of object to shadow is 10:6. Therefore if the object is 3, the shadow is 1.8 ( 6/10x3).
If the tree is T ft high, then T/21 = 8/3 so that T = 21*8/3 = 56 feet.
To cast a 19 foot shadow the building would have to be 26.91 feet tall. Each foot of building/tree casts 8.47 inches of shadow.

If a 27 ft tall pole casts an 18 foot shadow, a 63 ft tall pole casts an x foot shadow.Put 27/18 and 63/x.Cross multiply, get 27x=1134Divide by 27 on both sides, a 63 foot tall pole casts a 42 foot long shadow.
17.45 feet.

1. How high is a flagpole that casts a shadow of 45 ft at the same time a woman 5.5 ft tall casts a shadow 10 ft?
50 feet
40 ft
15 feet high
The man is twice as high as his shadow. Therefore, the tree must also be twice as high as its shadow, which would make the tree 40 feet tall.
The shadow:object ratio is 1:1 so the tree is 63 feet high.
