let x be the length of each of the lawn's side, and y be the length of each of the whole land's side (including the path surrounding the lawn) y^2 - x^2 = 165 y = x + 5 substitute y: (x+5)^2 - x^2 = 165 hence: x^2 + 10x + 25 - x^2 = 165 10x = 140 x = 14 a...

(5 x 50) + (5 x 70) - 25 = total area of the crosslands. As for how much cost is required, just times the cost of constrution. Because I dunno what you mean by "Rs. 20"

But how does the reaction allow you to differentiate? There's no color change or effervescence that can help you differentiate the two reactions right?
