Step-by-step explanation:

Given

See attachment for shapes

Required

The perimeter of B

Let the length of a side of the square that makes up A be, l.

So, we have:

--- because A is formed by 10 sides of l

The perimeter of B is:

--- because B is formed by 8 sides of l

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
