The expression for the area of frame is 4x² + 24x + 35

<h3>What is Area of rectangle?</h3>

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.

Here, Old length of photograph = 5 inch

          Old width of photograph = 7 inch

Now, length of new photograph = (5 + 2x) inch

        width of new photograph = (7 + 2x) inch

Now, Area of frame with new dimension = Length X breadth

                                                                     = (5+2x) X (7+2x)

                                                                     = 5(7+2x) + 2x(7+2x)

                                                                    = 35 + 10x + 14x + 4x²

                                                                    = 4x² + 24x + 35

Thus, the expression for the area of frame is 4x² + 24x + 35.
