Rosa’s room is 4 meters wide. Which of
these is an equivalent measurement?
A 0.28 mile
B 4.38 yards
C 12.4 feet
D 136.2 inches



Answer :

The answer is choice B. 4.38 yards because the unit conversion between meters to yards is 1 meter = 1.09361 yards.  4 meters X 1.09361 yards/1 meter = 4.37445 yards, closest to answer choice B. 4.38 yards.  Meters cancels out and we are left with units of yards.  
First, let's find the equivalent of 1 meter to each of the US Standard choices (inches, feet, yards, miles).
1 meter = 39.37 inches = 3.28 feet = 1.09 yards = 0.00062 miles
Now, to find the metric equivalent of each of the choices, we multiply each of these by 4 (since we need to find a measurement equivalent to 4 meters), and check them against the choices.
A. 0.28 miles.
0.00062 x 4 = 0.0025
0.0025 is much smaller than 0.28, so that won't work.
B. 4.38 yards
1.09 x 4 = 4.36
4.36 is 0.02 smaller than 4.38, so it's pretty darn close.
C. 12.4 feet
3.28 x 4 = 13.12
13.12 is slightly bigger than 12.4, but it's not as close as in B.
D. 136.2 inches
39.37 x 4 = 157.48
157.48 is considerably bigger than 136.2, so that doesn't work, either.
The two that are closest are B and C, but B is closer by far.
If you round to the nearest tenth, 4.36 becomes 4.4, and 4.38 becomes 4.4
This means that B, 4.38 yards, is as equivalent a measurement as you're going to get with these choices.
Therefore the answer is B: 4.38 yards.
