Answer: 3173 mm² (Answer C)
Area of the bottom triangle = 1/2 x base x height
Area of the bottom triangle = 1/2 x 19 x 23 = 218.5mm²
Area of the top triangle = area of the bottom triangle
Area of the top triangle = 218.5mm²
Area of the 3 side rectangles = (23 x 38) + (19 x 38) + (30 x 38)
Area of the 3 side rectangles = 2736 mm²
Total Surface area = 218.5 + 218.5 + 2736 = 3173 mm²

Did you learn how to factor the difference of two squares ?
This thing is the difference of two squares.
The first term is the square of 5x .
The second term is the square of 4 .
When it's factored, it's
(sum of the square roots) x (difference of the square roots) .
25 x² - 16 = (5x + 4) times (5x - 4) .
To check it, go ahead and FOIL that out, and you'll get 25x²-16 .
