Question

Find the length of the diagonal AD in the pentagon ABCDE shown in the coordinate plane. 5 units

Answer 1

`√(73)`units.

Step-by-step explanation:

We have given a pentagon ABCDE

We need to calculate its length

That means we have to find the distance of AD

So, coordinates of A(1,6) and D(4,-2)

Using distance formula:

Here,

On substituting the values we will get:

On simplification:

Hence, the length of AD is units.
