1. Problem Description

We need to find the perimeter of the given shape. The perimeter is the sum of all the sides of the shape.

2. Solution Steps

The shape has sides with lengths $2.5 m$, $1 m$, $2 m$, and $1.5 m$, and $1 m$.

Perimeter = Sum of all sides.

Perimeter $= 2.5 + 1 + 2 + 1.5 + 1$.

Perimeter $= 2.5 + 1 + 2 + 1.5 + 1 = 8$.
