The answer above is not correct. Find the area of the triangle with vertices (-1, -2), (7,0), and (2,4).
Added by Brian B.
Step 1
Find the length of each side of the triangle using the distance formula: - Side 1: sqrt((7-(-1))^2 + (0-(-2))^2) = sqrt(64+4) = sqrt(68) - Side 2: sqrt((2-7)^2 + (4-0)^2) = sqrt(25+16) = sqrt(41) - Side 3: sqrt((2-(-1))^2 + (4-(-2))^2) = sqrt(9+36) = sqrt(45) Show more…
