What is the area of a triangle whose vertices are d(3, 3) , e(3, −1) , and f(−2, −5) ? enter your answer in the box. __units²

Answer        

Find out the Area of a triangle .

To proof  

Formula

Area of Triangle

Now vertices are D(3, 3) , E(3, −1) , and F(−2, −5) .

Solving the above

= -10 units²

(Neglected the negative sign as area cannot be negative.)

= 10 units ²

Area of  a triangle is 10 units ²

Hence proved
