I found the definition of "measure" in merriam-webster dictionary.<br/><br/>3. [linking verb] <b>:</b> to have a specified size ? The cloth <u>measures</u> 3 meters.? The room <u>measures</u> 15 feet wide by 30 feet long.<br/><br/>Q) If I change "measures" in the examples to "is," what's the difference?
