Determine and state the area of a triangle PQR, whose vertices have coordinates P(-2,-5), Q(3,5). and R(6,1)

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

i think the amount would be $140.62
