Answer:
36 centimeters squared.
Step-by-step explanation:
Use the formula for the area of a square.



First u have to expand the brackets...
4 x 2z = 8z
4 x 3 = 12
8z + 12 = 12
Then you have to get numbers on one side, and letter on the other...
8z -12 = 12-12
8z = 0
then u have to divide 8z by 8 to find 1z or just z.
z = (0/8) = 0
z=0
Hope this helps :)
