Answer:
Area of triangle = 44.104 cm²
Explanation:
Formula:-
Area of triangle = bh/2
where b - Base and h - Height
To find the height of triangle
Let h be the height of triangle then we can write,
Sin 63 = h/11
h = 11 * sin 63 = 11 * 0.891 = 9.801 cm
To find the area of triangle
Area = bh/2
= (9 * 9.801)/2 = 44.104 cm²
