Area of rectangles = width * length.
So x*12 = 12x = area of first rectangle
So 16*(x-2) = 16x -32 = area of second rectangle

The question states to make them equal, so:
first rectangle = second rectangle
12x = 16x -32
Solve for x
-4x = -32
4x = 32
x = 8

3. Surface area of prism = 2(wl + hl + hw)
l = 15 , w = 3 and h = 4
2(3*15+4*15+4*3)
2(45+60+12)
2(117)
234
Surface area of rectangular prism is 234mm^2
