Find the length of CD

D

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = C(3, - 2) and (x₂, y₂ ) = D(7, - 8)

CD =

      =

      =

       = ≈ 7.2 → D

Length of CD is 7.2 unit approx Option D.

Step-by-step explanation:

Given,

The two points are C(3,-2) and D(7,-8).

To find the length of CD.

Formula

The distance of two points () and () is

Now,

Putting,

we get,

CD =

= = 7.2 (approx)

thats one
