Approximately how many meters are equal to 11.4 feet?Note: 1 m≈3.3 ftRound your answer to the nearest hundredths.

notka56 [123]

Alright, lets get started.

We are asked, approximately how many meters are equal to 11.4 feet.

We have given that,

3.3 feet = 1 meter

So, 1 feet = $\frac{1}{3.3}$ meter

So, 11.4 feet = $11.4 *\frac{1}{3.3}$ meter

11.4 feet = $\frac{11.4}{3.3}$ meter

11.4 feet = 3.45 meters : Answer

Hope it will help :)
