There is a formula which employs the use of determinants and which helps us calculate the area of a triangle if the vertices are given as . The formula is as shown below:
Area=
Now, in our case, we have:
, and
Thus, the area in this case will become:
Area=
Therefore, Area=
We know that area cannot be negative, so the area of the given triangle is <u>10 squared units</u>.
Answer:1490
Step-by-step explanation:so while solving this question, you want to make sure the decimals are on top of each other. 8+8 is 16 so you write 6 and carry 1. 4+9 is 13 +1 =14, write 4 carry one across the decimals. 5+4 is 9 plus 1 equals 10 write zero carry 1. 7+1 is 8 plus 1 is 9 so you write that down and since 1 and 4 have no numbers under them, you write it down too giving you 1490.46
