there are two ends and three lateral faces, so
2A + (2+3+4)*7
to find the area of the triangular bases, draw an altitude to the base of length 4. That line divides the base into two parts of length x and 4-x. Then, if the height is h,
h^2+x^2 = 4
h^2+(4-x)^2 = 9
x = 21/8
now find h, and
the area is (1/2)(4)(h)
