The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to S(3, 4) and continues to T(3, −1). The total length of the walking trail is ___

Respuesta :

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ [tex]RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

⇒       [tex]=\sqrt{(3-(-2))^2+(4-4)^2}[/tex]

⇒       [tex]=\sqrt{(3+2)^2+(0)^2}[/tex]

⇒       [tex]=\sqrt{25}[/tex]

⇒       [tex]=5 \ units[/tex]

and,

⇒ [tex]ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

⇒       [tex]=\sqrt{(3-3)^2+(-1-4)^2}[/tex]

⇒       [tex]=\sqrt{0+(-5)^2}[/tex]

⇒       [tex]=5 \ units[/tex]

Now,

The total trail length will be:

= [tex]RS+ST[/tex]

= [tex]5+5[/tex]

= [tex]10 \ units[/tex]
