Step-by-step explanation:
Area of Square ABCD = 10m * 10m = 100m².
Basically you just have to plug in g(x) wherever you see an x in the equation f(x) since x is f(x) you just substitute it . So f(g(x))=2x+3
You then just have to solve for 0
0=2x+3
Subtract 3 from both sides
-3=2x
Divide by 2
X=-3/2

So, now your going to add 14 cm to 30 cm, giving you 44 cm. But, if you do that then you will have to subtract 14 cm from the other board. That leaves you with the bigger board is 44 cm, and the smaller one is 16 cm.
