Perimeter of triangle is 18.

Step-by-step explanation:

Given:

segment PQ = 1.8

segment PR = 8.2

∠PQR =90°

Since triangle is a right angle triangle with right angle at ∠Q.

Now by using Pythagoras theorem we get;

The square of one side is equal to sum  of the square of other two side.

Substituting the given value we get;

Now taking square root on both side we get;

Now we need to find the perimeter of the triangle.

Perimeter of triangle is sum of all three side.

Framing in equation form we get;

Perimeter of triangle = PQ + QR +PR = 1.8 + 8 + 8.2 = 18

Hence Perimeter of triangle is 18.
