Answer:
The height of the lighthouse is 48 feet
Step-by-step explanation:
The question is incomplete but I presume the complete question is asking that the height of the lighthouse (in feet) should be calculated;
I'll answer this question based on that assumption;
Given
Shadow of lighthouse, S = 36ft
Height of Zara, h = 4ft
Shadow of Zara, s = 3ft.
We're to calculate the height of lighthouse, using the given data.
First, we need to calculate the magnifying ratio, M.
For Zara, M = s/h
M = 3/4
For the lighthouse,
M = S/H = 36/H
Since, M = M; We have
36/H = 3/4 ---- Make H the subject of formula
H = 4 * 36/3
H = 4 * 12
H = 48 feet
Hence, the height of the lighthouse is 48 feet
Answer:
The light house is 48 feet tall
Step-by-step explanation:
From Zara information:
Zara is 4 feet tall.
Zara shadow is 3 feet long.
We can see the ratio actual tallness to shadow length to be 4 : 3
i.e actual tallness : shadow length
= 4:3
Since we have the shadow length of the light house to be 36feet
Let x represent the tallness of the light house.
= 4 : 3
= X : 36
4/3 = x/36
3x = 144
x = 144/3 = 48
The light house is 48 feet tall
