40 points!

What is the area of a triangle with vertices at (-3,3),(2,3),and(4,7)?

B

Step-by-step explanation:

area of a triangle is  ( base * length )/2

so you can see that two points have the same y value < (-3,3) and (2,3)

both are on the same line of y = 3.

so the next value of y = 7      < (4,7)

that means that the length between the two values is 7-3 = 4

now u have your length

now just find the length between the two x-values of the first two points

2- (-3) = 5

that means that the base is 5 units long

so substitute the values

(5x4)/2

= 10 square units

10 square units
