HELP URGENTLY 1 QUESTION PLEASE SUPER QUICC
Zepler [3.9K]

So the formula for the area of a triangle is A=\frac{1}{2} bh (b = base, h = height). In this case, by counting from (-3,-3) to (-3,2) the height is 5 and the base is 4 counting from (-3,2) to (1,2).


Using this info, we can form the equationA=\frac{1}{2} *4*5 and solve from there.


A=\frac{1}{2} *4*5\\ A=\frac{1}{2} *20\\ A=10
