recruit someone to stand against the wall below the ceiling you wish to measure, or you can use an object like a door, store fixture, or window - just know its height.
stand about 20 feet in front of the same wall. extend your arm in front of you and \measure\ the persons height using your thumb and index finger as shown.
continue \measuring\ up the wall with the original spacing established between your thumb and finger until you reach the ceiling.
take your friends approximate height and multiply it by the number of \measurements\ from the floor to the ceiling.
6 times 2.5 = 15... we have 15 ceilings!
17 feet
16.5 feet
16.25 feet
16 feet

Explanation:

Step1: Identify the given values

Friend's height = 6.5 feet, Number of "measurements" = 2.5

Step2: Use the multiplication formula

The estimated ceiling height is found by multiplying the friend's height by the number of "measurements". So, the calculation is $6.5\times2.5$.
$6.5\times2.5=(6 + 0.5)\times2.5=6\times2.5+0.5\times2.5 = 15+1.25=16.25$ feet

Answer:

16.25 feet
