Question

Apple 18m high cast a shadow of 12 m at the same time if the length of the shadow of a tree is 4m then the height of the tree​

Answer 1

Answer:

6m

Step-by-step explanation:

Object : Shadow = 18 m : 12 m

Find the Ratio:

Object : Shadow = 18 : 12

Simplify by dividing by 6:

Object : Shadow = 3 : 2

Find the length of tree given the shadow is 4m:

Object : Shadow = 3 : 2

Multiply by 2:

Object : Shadow = 3x2 : 2x3

Object : Shadow = 6 : 4

Therefore the height of the tree is 6m

Answer 2

The angle between the tree and ground and the angle between the so called apple and ground is both 90 degree.

Also Angle of elevation of sun is also same at same time .

Hence the two triangles formed are similar.

NOW,

18/Height of tree=12/4

Height of tree=18×4/12

=6m .
