Xy=18
y=2x
y = 18/x
y = y
2x = 18/x
2x(x) = 18(1)
2x^2 = 18
x^2 = 18/2
x^2 = 9
so x = square root of 9 = 3
x = 3.

Answer:
a=1.5, b= 3
Step-by-step explanation:
sum of all sides will give us perimeter. Therefore
2a+b+6a+2b+1+4a=28
12a+3b+1=28
12a+3b=27....eqn1
since t two sides of this isosceles triangle are equal:
2a+b=4a
2a=b

substituting 
in the first equation whenever we encounter a we will have:

6b+3b=27
9b=27
b=3
therefore
