What is the area of a triangle whose vertices are d(3,3), e(3,-1), and f(-2,-5)?

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 10 squared units.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
