Question

If the vertices of BCD are B(–3, 3), C(3, 5), and D(–1, 0), what is the perimeter?

Answer 1

For this question you need to coordinate geometry to find the distance between the coordinates then find the perimeter

Answer 2

Answer:

16.33 units.

Step-by-step explanation:

Given are the vertices of triangle BCD as B(–3, 3), C(3, 5), and D(–1, 0).

Side CD = 6.403   DE= 3.606   EC = 6.325

using distance formula between two coordinates.

Distance between (x1,y1) and (x2,y2)

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

Perimeter = sum of all sides

= 6.403+3.606+6.325

= 16.332
