P=2(L+W)
P=78
L=3+2W
78=2(L+W)
divide both sides by 2
39=L+W
sub 3+2W for L
39=3+2W+W
39=3+3W
minus 3 both sides
36=3W
divide both sides by 3
12=W
width=12
sub back to find length
L=3+2W
L=3+2(12)
L=3+24
L=27
it is 12 by 27
82 82 82 82 82 82 its flipping 82 but if you want to get technical then its 82.645833 I'm literally a math genius if you want more math friend me and get back at me
i do almost everything in my head
2x and (2x +2)
2 * 2x + 2x + 2 = 62
6x = 60
x = 10
So 2x = 20 (one of the integers) and 22 is the other
