The expression represents the perimeter of the triangle as 18w + 2x + 6 cms.
Given, the length of sides of the triangle are (10w + 7)cms , (8w -2)cms, (2x + 1) cms.
We have to find the expression for the perimeter.
The formula to find the perimeter is-
The perimeter of the triangle = sum of all sides
= (10w + 7) + (8w - 2) + (2x + 1)
= 10w + 8w + 2x + 7 - 2 + 1
= 18w + 2x + 6 cms.
Hence, the perimeter of the triangle is represented as 18w + 2x + 6 cms.
