Answer:
1.10 units.
Explanation:
One side of the polygon measures 2.2 units. It is reflected along the x-axis. Since reflection preserves the size and the shape of the polygon, this means that the size of the first image of the polygon will remain unchanged. Second transformation is the dilation done by the factor k = 0.5. Dilation changes the size of the shape according to the dilation factor. If the original length of AB is 2.2, then the length of LM will be calculated by multiplying the original length with the dilation factor. Therefore, LM = 2.2 * 0.5 = 1.10 (correct to 2 decimal places).
Therefore, the length of LM is 1.10 units!!!
