The answer is 1 5/24 or 1.20833
1) P=2w +2l
46=2w +14
32=2w
16= w or width
2) A=lw
A=7 x 12
A= 84
3) A= 12 x 21
A= 252
A) high transparency of visible light
significance= allows photosynthesis to happen and speed up chemical reactions
b) high cohesion because of hydrogen bonding
significance= transport of water relies on water being pulled up around the plant.
