35.39, 35.38, 35.37, 35.36 are some numbers that round to 35.4 when rounded to the nearest tenth
Answer: There are 
in one inch.
for the triangle...
b=2h
a=(1\2).bh=648
(1/2).2h.h=648
h2=648
h-18|2 in
h=36|2 in
for the rectangle...
L=3+w
a=l+w=648
{3+w}w=648
w2+3w-648=0
Only positive W values make sense here..
w-24=0
w=24 in
So..
L=3+24
13 red, 5 blue, 7 green...for a total of 25
percentage of green ones is : 7/25 = 0.28 = 28% <==
