No wonder you have posted this. It is not easy. Scale is a straight line measurement. You need to use a side of a square.

Left: 1 side of a square = 1 meter.

Center: 3 tops of a square = 1 meter.
Therefore 1 side of a square = 1/3 of a meter.

Right: 1 side of a square = 0.5 meters.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
