Step-by-step explanation:

  1. a . write the formula for finding area that is area= L by W so to get w will area over length so 4731/83= 57
  2. perimeter=2( L+ W ) so substitute so that it looks like this 318= 2(L + 72 ) then open the bracket 318= (2L + 144) then move 144 to the other side so 318 - 144 = 2L then you get 174= 2L divide both sides by 2 and your length is 87
