To find the height of the triangle we can use pythagorean theorem or a squared to b squared = c squared with c as the hypotenuse.
14 squared + height squared = 16 squared
196 + height squared = 256
height squared = 60
height = 2[tex] \sqrt{15} [/tex]
The formula for surface area or total area is:
perimeter x height + 2 x area of base
30 + 2[tex] \sqrt{15} [/tex] + 28[tex] \sqrt{15} [/tex]
30 + 30[tex] \sqrt{15} [/tex] = final answer
Hopes it helps!
