answer: 28 inches squared
step-by-step explanation: i split this up by rectangles, to make it easier to visualize.
the top horizontal rectangle has a side length of 4 inches and a height of 2, (4 x 2) making the area 8.
the top and bottom rectangles have the same side lengths and heights (4 x 2), so therefore the bottom rectangle also has an area of 8 inches squared.
the middle/vertical rectangle has a side length of 2 and a height of 6, making its area 12.
to find the area of the entire face, you would add the three together.
12 + 8 + 8 = 28 inches squared.
i provided a photo of the split-up rectangle, in case you're a more visual learner, or in case i explained it awkwardly.
hope this helps! :)
