Answer:width is 9ft
Length is 12 ft
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The area of a triangle is expressed as length, L × Width, W.
Area of the rectangular pen is 108 ft^2. Therefore,
LW = 108 - - - - - - - 1
if the width is 3 feet less than the length, it means that
W = L - 3
Substituting W = L - 3 into equation 1, it becomes
L(L - 3) = 108
L^2 - 3L = 108
L^2 - 3L- 108 = 0
L^2 + 9L- 12L - 108 = 0
L(L + 9) - 12(L + 9) = 0
L - 12 = 0 or L + 9= 0
L = 12 or L = - 9
The length cannot be negative,
so Length = 12ft
W = 108/L = 108/12 = 9 ft
Answer:
Number each of the treatments 1 — 3 and place them into a hat.
Step-by-step explanation:
Number each of the treatment I — 3 and place them into a hat. Shake the hat vigorously to mix the lumbers. Then for each plot of land, draw out a umber. The number drawn out from the hat will represent the treatment that will be imposed on the plot.
The number drawn out of the hat will be replaced and another number will be drawn for the next plot of land. Then, at the end of the experiment, the plant biomass of each plot will be measured and an average will be taken for all three treatments to determine which treatment had the greatest effect on plant biomass.
