Answer 2

Given,

The height of the tower Th = 50m.

Tower shadow Ts = 30m.

Lighthouse shadow Ls = 60m.

To Find,

The height of the lighthouse.

Solution,

Given that,

The tower's height Th = 50m.

The shadow of tower Ts = 30m.

The lighthouse's shadow Ls = 60m.

Let's take the lighthouse height= Lh

Therefore, to find the height let's compare the given values.

50 / 30  =  Lh / 60

Lh = (50 × 60) / 30

Lh = 3000 / 30

Lh = 100m.

Hence, the lighthouse height which produces a shadow of 60m long is 100m.
