Perimeter = 2(Length + Width) = 2*(x+1 + x-3) =2*(2x - 2) = 4*(x - 1)
2 x 8 metres plus 2 x 3 metres = a perimeter of 22 metres.
1 + 2 + 3 = 6

By ratios Lineaer 1:2 sides ::: 1: 2 perimeter. Area 1:2 sides ::: 1^(2) : 2^(2) Area or 1:2 :: 1:4 Volume 1:2 sides ;; 1:8 volume Algebriacally, Linear a ; b ;; a: b Area a:b :: a^(2) : b^(2) Volume a:b :: a^(3):b^(3)
1 + 2 + 3 + 4.99 = 10.99
1 + 2 + 3 + 4.1 = 10.1
2/3 plus 2/3 equals 4/3 or 1 1/3.
