Answer:
[tex]area = (6 + 2y) \times (8 + 2y)[/tex]
Step-by-step explanation:
when we visualize this problem, we see that for each dimension, we add 2y to its size. for width, we add y for the left and right sides of the frame, and for height, we add y for the top and bottom parts.
this gives us the dimensions of the frame in terms of the dimensions of the picture and y:
the frame is (6+2y) by (8+2y)
the area of a rectangle is calculated by multiplying its side-lengths, so we get:
[tex]area = (6 + 2y) \times (8 + 2y)[/tex]
