The area under the line in a velocity-time graph represents the distance travelled. To find the distance travelled in the graph above, you need to find the area of the light-blue triangle and the dark-blue rectangle. The width of the rectangle is 6 seconds and the height is 8 metres per second.

**Explanation:**
The distance covered by a body can be determined from a velocity-time graph by finding the area under the graph. This is because the area under the graph represents the displacement of the body over a certain time interval.
**Area Under the Graph:**
When we calculate the area under the graph, we are essentially finding the sum of all the small rectangles formed by the graph. Each rectangle has a width of Δt (change in time) and a height of v (velocity) at that particular point in time.
Since the formula for the area of a rectangle is A = base × height, the area under the graph can be calculated by summing up the areas of all the rectangles:
\[Area = v_1 \times \Delta t_1 + v_2 \times \Delta t_2 + v_3 \times \Delta t_3 + \ldots\]
Simplifying the equation, we get:
\[Area = \Sigma v \times \Delta t\]
where Σ represents the sum of all the velocities and time intervals.
**Interpretation of Area:**
The area under the graph represents the displacement of the body. This is because the velocity of the body multiplied by the time interval gives us the distance traveled during that time interval.
By summing up the areas of all the rectangles, we are essentially calculating the total distance covered by the body over the entire time interval.
**Conclusion:**
Therefore, the correct answer is option B: The distance covered by a body from a velocity-time graph is equal to the area under the graph.
