In 1866, the U. S. Congress defined the U. S. yard as exactly 3600/3937 international meter. This was done primarily because:a.there are more wavelengths in a yard than in a meterb.this definition relates the common U. S. length units to a more widely used systemc.the meter is more stable than the yardd. length can be measured more accurately in meters than in yardsQuestion 2 of 283.

There is no SI base unit for area because:a.we live in a three (not a two) dimensional worldb.area can be expressed in terms of square metersc. it is impossible to express square feet in terms of metersd.an area has no thickness; hence no physical standard can be builtQuestion 10 of 2811.
