Question

a polygon has the following coordinates: A(-4,-5), B(-2,-3), C(4,-3), D(6,-2), E6,6), F(-1,6), G(-4,2). Find the length of GA.

Answer 1

GA = 7.

We use the distance formula to answer this:

$d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\ \\=\sqrt{(2--5)^2+(-4--4)^2} \\ \\=\sqrt{(2+5)^2+(-4+4)^2}=\sqrt{7^2+0^2}=\sqrt{49}=7$
