Answer» Answer: 225 m² Step-by-step explanation: Let length of side of lawn = X So, the AREA of the lawn = x * x = x² Now, given width = 5 m So, the length increased by 5 + 5 = 10 m Now, area of the path including width = (x + 10)*(x + 10) Given, area of the path = 400 => (x + 10)*(x + 10) - x² = 400 ⇒ 20x = 300 => x = 15 So, the side of the lawn = 15 m Hence, area of the lawn = (15)² = 225 m²Hope it HELPS!
