Question

Find the area of the triangle.area triangle 3A. 11.1 cm²B. 11.3 cm²C. 111.4 cm²D. 24.8 cm²

Answer 1

To calculate the area of this triangle, we use the SAS area formula. Given two sides a and b, and the inscribed angle between them c, the area of a triangle is given by the following formula:

`A=a* b*\sin(c)`

Using the known values of the figure on this formula, we have:

`A=11*4.9*\sin113^o\approx24.8`

The answer is option D. The area of this triangle is 24.8 cm².
