What a terrible question. I'm sorry you have this teacher. I think the answer they are looking for is 42 even though there's that +/- should be in a parenthesis and then you are rounding 6.5² to 42. Hope this helps
V = (64h)^.5
v = (64 * 84)^.5
v = (5,376)^.5
v = <span>73.3212111193
Round to the nearest hundreath
v = 73.32
Hope I helped!!!</span>
