Answer:
i almost feel bad-
Step-by-step explanation:
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! :)
Since we are adding two positive numbers here, their sum could be found by writing either
8
+4

12
or
4
+8

12
Answer:
least: 4 tons, greatest: 8 tons
Step-by-step explanation:
.4 round down (5 and up, round up rule)
.7 round up
Welp, it can't get any easier. Now, they give you the value for l (length which is 12.9) and the give you the value for w (width which is 19.3)
Now, you'd just plug them in. So
P = 2(12.9) + 2(19.3)
=25.8+38.6
=64.4ft
