Answer:

Step-by-step explanation:
In order to find the area of a square you take the base and multiply it by the height.
Base x Height = Area

All you have to do after that is multiply the two together.
Make sure that you remember to put the unit (cm) and make sure that it is
because some teachers are uptight about that stuff.

2a^2+2b-12=0 is not a solvable quadratic. I will assume you meant 2x^2+2x-12
The quadratic formula is (-b+-sqrt(b^2-(4ac))/2a
(-2+-sqrt(2^2-(4*2*-12))/2*2
(-2+-sqrt(4-(-96))/4
(-2+-sqrt(100))/4
(-2+-10)/4
12/4 or 8/4
3 or 2
The answer is x=3 or x=2
