Answer:
p=11/2
Step-by-step explanation:
there are algebra calculators
79.2% is 0.792 as a decimal
LongSong = 286s
LongSong = 2 * ShortSong - 126s
=>
2 * ShortSong - 126s = 286s
2 * ShortSong = 286s + 126s
2 * ShortSong = 412s
ShortSong = 206s
Answer:

Step-by-step explanation:



Let the width of the field = x.
Then the length = 4x
Now the perimeter = 2 * length + 2 * width, so we have the equation:-
2*4x + 2x = 340
8x + 2x = 340
10x = 340
x = 34 yards = width
4x = length = 136
Answer: the width is 34 yards and length is 136 yards.
