Question

Tracy is cutting out a rectangular board to construct a bookshelf.

The board is to have a perimeter of 38 inches, and its length is to be 5 inches shorter than double the width.

Let x be the width of the board.

State the expression for the length of the board in terms of x.

Answer 1

28 inch

Explanation:

half of 38 would be 19, and take away 5 from both 19. Equally each width ( top and bottom ) 14 inch and each lenght ( Left and right ) 5 inch. so x representing width would be 14 + 14= 28 inch.
