Question 292590: Perimeter of a triangle.
The lengths of the sides of a triangle are 1x , 21x , and 32x meters. Find a rational expression for the perimeter of the triangle.
***Again rational expressions i do not understand how to write. My best try at this i came up with:
perimeter = 1x + 21x + 32x. The permiter of anything is adding all the sides to gether. Am i correct in my thinking??

They want just an expression not an equation.
1x + 21x + 32x
combine
54x
