please :(

domebotnos · Answer

l - 5 = x + 1 because a square sides are equal.  Then solve:
l - 5 = x + 1
  -1          -1
l - 6 = x

Post it in another question.

what is the width of the land in meters

anonymous · Answer

its the same question

domebotnos · Answer

solve for y
l - 5 = x + 1
  + 5      + 5
l = x + 6
Plug it into the other equation.
l*x = 280
(x + 6)*x = 280
x^2 + 6x = 280
   -280       -280
x^2 + 6x - 280
Then factor for the only reason answer.  One will be positive the other negative.
