Explanation: 2(l + b) = 110 l + b = 55 I. 2(l + b) = 110 I. 2(l + b) = 110 I. 2(l +),II. l = (b + 5) l - b l - b l - b l - b l - b l,l/b = 6 /5 5l - 6b = 0 III. l/b = 6 /5 5l - 6b = 0 These are three l and b equations. We may solve them in pairs.The solution can be found in any two of the three options.
