the width is x/2x-5

the length is 8/2x-5

P=2l+2w

p=2(8/2x-5)+2(x/2x-5)

p=(16/2x-5)+(2x/2x-5)

p=2x+16/2x-5

Correctbut use parentheses to group your operations

the width is x/(2x-5)

the length is 8/(2x-5)

P = 2l + 2w

p = 2[8/(2x-5)] + 2[x/(2x-5)]

p = 16/(2x-5) + 2x/(2x-5)

p = (2x+16)/(2x-5) = 2(x+8)/(2x-5)
