What is the area of △abc? enter your answer as a decimal in the box. round only your final answer to the nearest tenth. m² a scalene triangle a b c. the base b c is labeled as 25 meters. side a b is labeled as 40 meters. angle b is labeled as 80 degrees.

Area = 492.4 m²

Explanation:
The area of the triangle can be calculated using the side-angle-side method as follows:
Area = 0.5 * first side * second side * sin(angle included between these two sides)

This rule is illustrated in the attached image.

Now, we have:
AB = 40 m
BC = 25 m
angle B which is the angle included between AB and BC = 80 degrees

The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.
Area of triangle = 0.5*40*25*sin(80)
Area of triangle = 492.4 m²

Hope this helps :)
