Let x = length and y = width
You would have 2 lengths, so 2x and 3 widths, so 3y
Those need to equal total length of fence:
2x + 3y = 1200
The 3 widths would equal total fence minus the 2 lengths:
3Y = 1200-2x
Solve for y: y = 400 -2/3x
Area = length x width = xy. Replace y :
Area = x(400-2/3x) = 400x-2/3x^2
Differentiate:
400-4x/3 =0
4x/3 = 400
4x = 1200
X = 300
Y = 400-2/3(300) = 200
The dimension would be 300 ft x 200 ft

Actually, you have to find four missed terms of geometrical sequence. Denote
and r - ratio, then
.
Since 
, you have that 
, then
.
Now substitude r=2 in each of unknown 4 terms:
.
Answer: four geometric means between 25 and 800 are 50, 100, 200, 400.
Step-by-step explanation:
Find the MEAN with the information you have. Then say th edifference between the mean on the graph and the median.
Let’s make common denominator
1/4 * 2/2 = 2/8 before dinner
1/8 after dinner
2/8 + 1/8 = 3/8
He finished 3/8 of the report
