Answer:
the value of g is -4
Step-by-step explanation:

Our aim is to solve for g
multiply 10 inside the parenthesis

Now combine like terms
Subtract 5g from both sides


Divide both sides by -1

P=32cm
A= 64cm^2
Step by Step
Formula(Perimeter): P=s+s+s+s
S=side P=perimeter
P=8*4
P=32
Formula(Area for Square): A=s^2
A=Area s=side
A=8^2
A=84
