Answer 1

Given:

The perimeter of a polygon is the sum of the lengths of the sides of the polygon.

Given that the sides of the polygon are x + 1, 3x - 2, 3x - 2, x + 1.

We need to determine the perimeter of the polygon.

Perimeter of the polygon:

The perimeter of the polygon can be determined by adding the lengths of the sides of the polygon.

Thus, we have;

$Perimeter=(x+1)+(3x-2)+(3x-2)+(x+1)$

Removing the parenthesis, we get;

$Perimeter=x+1+3x-2+3x-2+x+1$

Adding the like terms, we get;

$Perimeter=8x-2$

Thus, the perimeter of the polygon is $8x-2$
