The area of a rectangle is 490490 in squaredin2. the ratio of the length to the width is 5 : 25: 2. find the length and the width.

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

Hi!

Well, the answer is 1.00
You see, we call the first number after the decimal "tenth" in this case that number is 9. If the digit in the next smallest place value is less than five, you leave the digit you want to round to as-is. Any digits after that number become zeros. This is called rounding down.If the next smallest place value is greater than or equal to five, you increase the value of the digit you're rounding to by one . Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are drop-offs This is called rounding up!

Have a nice day!
