Work out the area of triangle give your answer to 1 decimal place

Given:

Given that the triangle.

Let the length of the side a be 10 cm.

Let the length of the side b be 13 cm.

Let the measure of ∠C is 105°

We need to determine the area of the triangle.

Area of the triangle:

The area of the triangle can be determined using the formula,

Substituting a = 10, b = 13 and ∠C = 105°, we get;

Simplifying, we get;

Rounding off to 1 decimal place, we have;

Thus, the area of the triangle is 62.8 cm²
