Answer:
3 metres
Step-by-step explanation:
Let the width of the pathway be x
Area: (9+2x)(4+2x)
36 + 8x + 18x + 4x²
4x² + 26x + 36
Increased area is 150:
4x² + 26x + 36 = 150
4x² + 26x - 114 = 0
2x² + 13x - 57 = 0
2x² + 19x - 6x - 57 = 0
x(2x + 19) - 3(2x + 19) = 0
(x - 3)(2x + 19) = 0
x = 3, x = -19/2
-- 'Truncated' to one decimal place, it's 9.9 ,
-- 'Rounded' to one decimal place, it's 9.9 .
(These two operations don't always produce the same result.)
To do this multiply 1840 by 182. This gives you 334,880.
What’s the x your trying to find
