Question

A rectangle has perimeter 182 inches and length 52 inches what is the width

Answer 1

52+52=104      182-104=78      78/2= 39 
Width= 39 inches 

Answer 2

If the perimeter is 182, double the length which is 52 to get 104.  Subtract that from 182 to get 78. Divide that by 2 to get the width which is 39.
