14) p=a+b+c
15) A=
16) p-b-c=a
Step-by-step explanation:
12) 
13)
=W (multiply both sides by h)
14) take c to the other side of the equation( other side of the equal sign) it becomes a positive value
15) Divide both sides by 2
16) take b + c to the other side of the equation where it becomes -b-c
Answer:
1566
Step-by-step explanation:
20*50=1000
