Four children measure the length of a table which was about 2 m. Each of them used different ways to measure it.
(i) Sam measured it with a half metre long thread.
(ii) Gurmeet measured it with a 15 cm scale from her geometry box.
(iii) Reena measured it using her hand span.
(iv) Salim measured it using a 5 m long measuring tape.
Which one of them would get the most accurate length? Give reason for your answer.

Explanation

To determine which child would get the most accurate measurement of the table's length, we will analyze each child's method of measurement step by step.

### Step-by-Step Solution:

1. **Understanding the Length of the Table**:
The table's length is approximately 2 meters. To measure this accurately, we need a measuring tool that can cover this length without needing to be used multiple times.

2. **Sam's Measurement**:
