SA = 6a^2
Where 'a' is the side length.
Plug in what we know:
SA = 6(14)^2
Simplify the exponent:
SA = 6(196)
Multiply:
SA = 1176
If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
