Answer:
nothing definite can be said and square
In private correspondence with the author of the question, it was determined
that 'y' is the variable of integration.
Therefore, 'a' is a constant for purposes of this integration, and that whole
'a' business can be taken outside the integral.
Integral [a/(1-ay) dy] = a/(1-a) integral [dy/y] = a ln(y)/(1-a) + C
60 = 2 ( length + width )
<span>30 = length + width </span>
<span>Let length be = x and width = y </span>
<span>x+y = 30 </span>
<span>xy = 209 </span>
<span>4xy = 836 </span>
<span>( x+ y)^2 = 900 </span>
<span>( x+y)^2 - 4xy = 900-836 = 64 </span>
<span>( x-y)^2 = 64 </span>
<span>x- y = 8 </span>
<span>x+y = 30 </span>
<span>ADD 2x =38 </span>
<span>x = 19 </span>
<span>y = 11 </span>
