I think you should write the equation to find perimeter such as P = 2(L + W). So the expression is 2[2(x+y) + 3(x - y)]
Simplified as 2[(2x + 2y + 3x - 3y)]
2(5x - 1y) combined like terms
10x - 2y is the expression for the perimeter of the rectangle

A)
$x=0.\overline{24}\\
100x=24.\overline{24}\\
100x-x=24.\overline{24}-0.\overline{24}\\
99x=24\\
x=\dfrac{24}{99}=\dfrac{8}{33}$

b)
$x=0.2\overline{4}\\
10x=2.\overline{4}\\
100x=24.\overline{4}\\
100x-10x=24.\overline{4}-2.\overline{4}\\
90x=22\\
x=\dfrac{22}{90}=\dfrac{11}{45}$

c)
$0.24=\dfrac{24}{100}=\dfrac{6}{25}$
