Multiply the second equation by -2 so it would be 4x-14y=6 and the first is equation is also 4x-14y=6
So there is infinitely many solutions
The top base is : 14mm
The bottom base is: 36mm
The height is: 15mm
First you need to add the top and bottom bases together and divide it by 2
(14mm + 36mm) / 2
= 50mm/2
=25mm
Then you need to times it by the height
25mm x 15mm = 375mm^2
