Answer:
28 ft
Step-by-step explanation:
Let longer side of rectangle be 
and the shorter side be 
, thus we can write the ratio:
<em>Now putting 21 into S, we solve for L:</em>
Hence, length of longer side is 28 ft.
3.48 x 10^ -5
move the decimal point back to the first number that isn't zero, if the decimal is moved right 5 spaces, it will be 10^ -5 , if a number has a zero, such as 0.000104, it would be 1.04 x 10^ -4.
The number X is placed somewhere between 9 and 10. That's because 9 squared is 81 and 10 squared is 100.
