What length of fencing is required to surround a square field with area 250 m? Show your work. Give your answer to the nearest centimetre.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
