Thank you for the opportunity to help you with your question!

total area of the new roof = 23 ft * 18 ft

                                         = 414 ft^2


total cost =  total area in square foot  * cost for one square foot

               = 414 *  3.75 

               = $ 1552.5  ...................................ANSWER


 new roof cost = $ 1552.5


Please let me know if you need any clarification. I'm always happy to answer your questions.
