W= width L= length = 2W
Area of Rectangle= Length * Widthsubstitute the area and the value of L in the formula
28,800 m^2= 2W * W
28,800= 2W^2divide both sides by 2 in an effort to isolate the variable w
14,400= W^2take the square root of both sides
√14,400= W^2
we want the negative and positive root of the radicand (the number under the radical symbol - 14,400 in this case)
120= w OR -120= w
LENGTHL= 2W= 2(120)= 240 meters
ANSWER: The side lengths are W= 120 m; L= 240 m. Even though W= -120 too, it is not a valid solution in this case since a field cannot have a negative value.
Hope this helps! :)

Answer:
four
Step-by-step expif this is worng but i had a similar question and that as the answer
Answer:
Step-by-step explanation:
Perimeter of a rectangle=(length+width)×2
Let W=x, L=2x+2
25=[(2x+2)+x]×2
25=[2x+2+x]×2
Solve for x
25/2=3x+2
25/2-2=3x
25-4/2=3x
21\2=3x=7/2=x

Answer:
10 ft
Step-by-step explanation:
The midsegment length is the average of the other two lengths.
(QR +PS)/2 = TU
QR +PS = 2×TU . . . . . . . . . . . . . . . multiply by 2
QR = 2×TU -PS = 2(14 ft) -18 ft . . . subtract PS; substitute given values
QR = 10 ft
