Find the area of the triangle ​

305.9m
Area of a Triangle is 1/2 base X height
So (b)(h) = 2.1m X 19m=39.9m (210 cm = 2.1 m)
Now that we have the base which is 39.9m
We do the sides which is 1/2*28*19=266m
Now that we have the sides, we add the base which is 39.9m and the Height which is 266m, then we get our 305.9m

I hope this helped you. Goodluck, and please give me a Branliest if available. Thanks. :)

I’m pretty sure the slope would be 1 since the x and y values increase by 1

The right answer should be 6 but your not very specific
