let a and be be the bases.
The formula of the area is the following :
[tex] \frac{a+b}{2}\times h= \frac{a+b}{2}\times\frac{1}{2}=\frac{a+b}{4} [/tex]
Equating we get the equation:
[tex]\frac{a+b}{4} = \frac{3}{4} x- \frac{1}{4} = \frac{3x+1}{4} [/tex]
So, identifying we get two possible expression:
[tex]a=3x,b=1[/tex]
