Girls=3 units
3unit=30
divide both sides by 3
1unit=10
2+3=5
5 total units
1unit=10
times 5 both sides

Correct question:
Determine the area of a triangle with A=27.8° B = 107.3° c=4
Answer:
Area of the triangle is 5.04 units²
Step-by-step explanation:
Given;
A = 27.8°
B = 107.3°
C = 180 - (27.8 + 107.3) = 44.9°
c = 4
Now, we determine the remaining two sides of the triangle using sine rule

Apply Hero's formula;

Therefore, area of the triangle is 5.04 units²
R = kp/st
18 = 12k/(1/6 x 2)
18 = 12k/(1/3)
18 = 36k
k = 18/36 = 1/2
