Question

A tree is standing by the side of a building.1/3 if the height of the tree is above the building 's height. If the building is 12m high,find the height of the tree.

Answer 1

Answer:

18m

Step-by-step explanation:

Let the height of the building be x.

the of tree above the building be 1/3x.

12m + 1/3x = x

x - 1/3x = 12m

2/3x = 12m

x = 12m × 3/2

x = 18m

The height of tree is 18m.

Answer 2

Answer:

18m

Step-by-step explanation:

Let us suppose the height of tree be x metre

height of tree above the building= 1x/3

A.T.Q

12 + 1x/3 = x

12 = x - 1x/3

12 = 3x - x /3

12 = 2x/3

12*3 = 2x

36/2 = x

18 = x

Therefore, the height of tree is x metre = 18 m
