Triangle SAA

The triangle has one side long 71 m and its two internal angles is 60°. Calculate the perimeter and area of the triangle.

Result

p =  213 m
A =  2182.82 m2

Solution:

p=371=213 mp = 3\cdot 71 = 213 \ m
A=7122sin(π3)=2182.82 m2A = \dfrac{ 71^2}{2} \sin(\dfrac{\pi}{3}) = 2182.82 \ m^2
