6.75

The perimeter of the triangle is the sum of three sides of the triangle.

P= a+b+c

where a,b, and c represents the sides of the triangle.

In an equilateral triangle, all sides and angles are equal. Therefore,

P= 3a

a represents the side of the triangle.

P= 3 x 2.25

= 6.75

The perimeter of the triangle is 6.75cm.
