Jessie drew a picture for her grandmother. Her grandmother wants to frame it and find the total area of the picture and its frame. Write an expression that represents the area if the frame must be 5 inches longer than the picture and 2 inches wider than the picture.

A. l + w + 7
B. lw + 2l + 5w + 10
C. lw + 2l + 5w + 7
D. l²w² + 7lw + 10

I don't understand how to do this.
