Question

(05.05 LC)

Answer 1

The length of side PQ of the polygon is 7 units

Step-by-step explanation:

Given points are:

P(5, 4) and Q(−2, 4)

In order to find the length of PQ, the distance formula for coordinate geometry will be used.

The distance formula is given by:

$d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Here

(x1,y1) = (5,4)

(x2,y2) = (-2,4)

$PQ = \sqrt{(-2-5)^2+(4-4)^2}\\=\sqrt{(-7)^2+(0)^2}\\= \sqrt{49}\\= 7\ units$

Hence,

The length of side PQ of the polygon is 7 units
