The answer is:  [D]:  " 24 + 2w " .
___________________________________________
Explanation:
___________________________________________
Given: The formula for the Perimeter of a rectangle:
___________________________________________
   P = 2L + 2w ; 
  
                 in which:
                                P = perimeter ;
                                L = length = 12 units (given); 
                                w = width = unknown;
_______________________________________________________
           Find the perimeter, "P", in terms of "w" ; since "w" (width) is unknown; and considering the answer choices given; along with the information provided in the problem, we only have enough information to solve for the perimeter, "P", in terms of "w" ; 
_____________________________________________________
         So, given the formula/equation for the perimeter, "P" :
_____________________________________________________
       P = 2L + 2w ;  we know that:  " L = 12 units " ;
_____________________________________________________
       P = 2*12  +  2w  =  24 + 2w ;  which is:  "Answer choice: [D]" .

gtnhenbr [62]

Harriet works 42 hours a week. She gets paid £9.12 for each hour she works. An estimated amount Harriet gets paid in a week is £378

<h3>How to calculate the percent error?</h3>

Ssuppose the actual value and the estimated values after the measurement are obtained. Then we have:

Error = Actual value - Estimated value

Harriet works 42 hours a week. She gets paid £9.12 for each hour she works.

1 hour = £9.12

Estimated

£9 x 42 hours = 378

Actual

£9.12 x 42 hours = 383.04
