Question

culating perimeter and area using the distance formula
w (3, -2)
d (7, -2)
d = \sqrt{( )^{2}+( )^{2}}
d =

Explanation:

Step1: Recall distance formula

The distance formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$.

Step2: Identify coordinates

For points $W(3,-2)$ and $D(7,-2)$, we have $x_1 = 3,y_1=-2,x_2 = 7,y_2=-2$.

Step3: Substitute into formula

$d=\sqrt{(7 - 3)^2+(-2-(-2))^2}=\sqrt{(4)^2+(0)^2}=\sqrt{16}=4$.

Answer:

$d = 4$
