Answer:
44.1 cm².
Explanation:
To find the area of the triangle, we can use the formula:
Area = (1/2) * base * height
In this case, we have the lengths of two sides, 11cm and 9cm, and the included angle, 63 degrees. To find the height of the triangle, we can use the formula:
Height = side * sin(angle)
Plugging in the values:
Height = 9cm * sin(63°)
Height ≈ 9cm * 0.891007
Height ≈ 8.019063 cm
Now, we can calculate the area:
Area = (1/2) * 11cm * 8.019063 cm
Area ≈ 0.5 * 11cm * 8.019063 cm
Area ≈ 44.1043465 cm²
Rounding the final answer to the nearest tenth, the area of the triangle is approximately 44.1 cm².
