Question

Square ABCD has coordinates A(8,7), B(10, 2), and D (3,5). Find the coordinates of C.

Answer 1

Answer:

Step-by-step explanation:

Area = 1/2[x1(y2 – y3) + x2(y3 – y1) + x3(y1 – y2)]

Now by putting all the values in the formula, we will get

Area of triangle = 1/2 [2(0 – (-4)) + (-1)((-4) – (3)) + 2(3 – 0)]

                          = 1/2 [8 + 7 + 6]

                          = 21/2

So, the area of triangle is 21/2 square units.
