For this, we use the Pythagorean Theorem to calculate for the side length of the triangle. This can only be used given your triangle is a right triangle. It is expressed as:

c² = a² + b²

where c is the hypotenuse.

c² = 3² + 3²
c = 3√2

Therefore, the perimeter is,

P = 3 + 3 + 3√2 = 6 + 3√2 ----------> Second option

The perimeter of the triangle with the given dimension of leg is 6+3√2.

Option B)6+3√2 is the correct answer.

What is a triangle?

A triangle is simply a two-dimensional polygon with 3 sides and 3 interior angles.

Perimeter = a + b + c

First we we determine c using Pythagorean theorem

c = √( a² + b² )

c = √( 3² + 3² )

c = √( 9 + 9 )

c = √18

c = 3√2

Now, the perimeter of the triangle will be;

P = a + b + c

P = 3 + 3 + 3√2

P = 6+3√2

The perimeter of the triangle with the given dimension of leg is 6+3√2.

Option B)6+3√2 is the correct answer.
