Divide the numerator by the denominator to find out
Length = w+3
P = 2L +2W
50 = 2(w+3) + 2w
50 = 2w +6 +2w
50 = 4w +6
50-6 =4w-6
44 = 4w
44/4 = 4w/4
w = 11
l = 11+3
l = 14
50 = 2L+2W
50 = 2(14) + 2(11)
50 = 28 +22
50=50
Size is not preserved under dilation.
We get AB+BC = AC from the question.
this means that:
2x + 3 + 6x - 5 = 22
8x = 24
x = 3
Plot i = 200 seeds
Geminated = 57% of 200 = 0.57 x 200 = 114 seeds
Plot ii = 300 seeds
Geminated = 42% of 300 = 0.42 x 300 = 126 seeds
Total geminated seeds = 114 + 126 = 240
Total seeds = 200 + 300 = 500
Percentage = 240 ÷ 500 x 100 = 48%
