Date:2012-04-26 18:16:56 The length of a rectangular deck is 8 meters more than twice the width. The perimeter of the deck is 46 m. Find the length of the deck. Let Length of rectangular deck = l and breath of rectangular deck = b As per 1st given condition; l = 8 + 2b ........(1) as per 2nd given condition; 2(l+b) = 46 Put the value of "l" from (1) and we get; 2(8+ 2b +b) = 46 solve the values in the parenthesis and we get; 2(8+ 3b) = 46 Divide both sides by 2 and we get: 8+ 3b = 23 subtract 8 from side and we get; 3b = 15 divide both sides by 3 and we get; b = 5 Put the value of b in (1) and we get l = 8 + 2b         = 8 + 2 * 5     = 8 + 10     = 15 So, Length of rectangular deck = 15 breath of rectangular deck = 8 Hope this will help you.
