The required percentage error when estimating the height of the building is 3.84%.
How to calculate the percent error?
Suppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
Given that,
An estimate of the height, H meters, of a tall building can be found using the formula :
H = 3f + 15
where the building is f floors high.
f = 85
The real height of the building is 260 m.
H = 3f + 15
Put f = 85 in the above formula
H = 3(85) + 15
H = 270 m
Error,
[tex]E = \dfrac{270 - 260 }{260} \times 100\\\\E = 3.84 %[/tex]
So, the required percentage error is 3.84%.
