612/68 = 9
if you do not have a calculator, use this technique to solve.
To find the GCF, it can take some guessing and checking.
i started by dividing both numbers by 4: 612/68 = 153/17
now to see if 153 is divisible by 17, think about what number times 7 ends in 3.
9*7=63
then multiply 17*9=153
the answer than is 9

Answer:
Perimeter
P = P1+P2
P1 = 4a P2=2(a+b)
P1=4*5 P2=2(3+5)
P1=20 P2=2*8
P2=16
P = 20+16
P=36
Area
A=A1+A2
A1= A2=a*b
A1= A2=3*5
A1=25 A2=15
A=25+15
A=40
