The plant is 4 and 1/4 inches above ground
(34/4)-(17/4)=17/4
Answer: Upper right corner
You divide every value in the table over 120 as 120 is the grand total
So we have 28/120 = 0.23 in row 1, column 1
Then we have 14/120 = 0.12 in row 1, column 2
etc etc
Length = 4w-8
P =2L + 2W
54 = 2(4w-8) + 2W
54 = 8w -16 +2W
54 = 10w -16
54+16 = 10w -16+16
70=10w
70/10=10w/10
w=7
L= 4(7) - 8
L = 28-8
L =20
Check
P = 2w +2L
54 = 2(7) + 2(20)
54 = 14+ 40
54=54
