Let the width be 2w. Then the lenght is 5w. So:
(2w)(5w)=490
10w²=490
w²=49
w=±7
So, 2w=width=14 in; and 5w=length=35 in

The 3rd one is the right one!!!!!!!!!!!!!!!!!!
Answer:
The answer is False,
Step-by-step explanation:
The answer is False because in some expressions if there are parentheses and there is a subtraction problem in the parentheses but there is an addition problem in front of the parentheses that does not exactly mean that you do the addition first, this is because the subtraction is inside the parentheses and so since the subtraction is in parentheses it is done fist.
-7x+3y=-24+7x-2x+5y
-7x+3y=5x+5y-24
-12x-2y=-24
-7x+3y=-11
-36x-6y=-72
-14x+6y=-22
-50x=-94
Okay well I did something wrong
