1. Answer:

   [tex]p = 2(l + b) \\ 9.82 = 2(11.69 + b) \\ \frac{9.82}{2} = 11.69 + b \\ 4.91 – 11.69 = b \\ – 6.78 inch= b \\ [/tex]

2. Answer:

   perimeter = 39.92 inches

   2( length + breadth )= perimeter

   2 (11.69 + breadth) = 39.92

   11.69+ breadth =39.92 ÷2

   11.69+ breadth = 19.96

   breadth = 19.96 – 11.69

   breadth =8.27 inches
