The sum of the three values is 10.25 meters.
Here, we are given three measurements- 7.5m, 2.25m and 50cm
Since, we need to find the answer in meters, let us convert all the units to meters so that we can add them.
7.5 and 2.25 are already in meters so we do not need to covert them.
We only need to convert 50 centimeters.
As per mathematical conversions,
1 meter = 100 centimeters
This means that 50 centimeters will be,
100/2 centimeters = 1/2 meters
⇒ 50 centimeters = 0.5 meters
Now, we add all the given numbers,
= 7.5 + 2.25 + 0.5
= 9.75 + 0.5
= 10.25
Thus, the sum is 10.25 meters.
