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=1134
Divide by 27 on both sides, a 63 foot tall pole casts a 42 foot long shadow.

A vertical yardstick casts a 1 foot shadow and the same tree nearby casts a 15 foot shadow How tall is the tree?
That depends on the height of the yardstick whose height has not been given.
21 foot tree cast what length of shadow?
Depends what time of day it is ... how high the sun is. It keeps changing all day. No shadow at all at night.
What would be the length of the shadow of a 24 ft tree when a 40 ft tree casts a 16 ft shadow?
You have two similar triangles with one side the tree, and another the shadow Using the side with the tree, the ratio of the length of the triangles can be found: the triangles are in the ratio of 24 : 40 Thus divide the shadow of the 40ft tree by 40 to find out the length of shadow per foot of tree, and multiply this by 24 to find the length of the shadow of the 24 ft tree. This can be done by using the ratio as a fraction 24/40: → the shadow of the 24 ft tree is 16 ft × 24/40 = 9.6 ft

A 3 foot pole casts a 6 foot shadow A 4 foot pole casts an 8 foot shadow Use a linear equation to predict the length of a shadow cast by a 6 foot pole?
Shadow lengths are proportional to the heights of objects casting the shadows. Therefore, calling the shadow length l, the height h, and the proportionality constant k, l = kh. (The intercept is 0 because an object with no height casts no shadow.) Therefore, in this instance k = l/h = 6/3 or 8/4 = 2. then l(6) = 2 X 6 = 12 feet.
