The perimeter of this pentagon is 19x + 1

Expression for the Sum of Perimeters

Square Perimeter:

Side length: 4x

Perimeter: 4 * 4x = 16x

Triangle Perimeter:

Side lengths: X, x + 1, X

Perimeter: X + (x + 1) + X = 2X + x + 1

Sum of Perimeters:

Combine the individual perimeters:

Total perimeter = Square perimeter + Triangle perimeter

Total perimeter = 16x + (2X + x + 1)

Simplifying the expression:

Total perimeter = 16x + 2X + x + 1

Total perimeter = 19x + 1

Complete question:

Write and simplify an expression that represents the sum of the perimeters of the square and the triangle.

A square with side length 4x. A triangle with side lengths X, x + 1, X
