Let's assume the height of the girl is x.
According to the given information, the average height of 2 boys and 1 girl is 1.3m. We can write this as:
(1m + 1.5m + x) / 3 = 1.3m
Simplifying the equation, we have:
(2.5m + x) = 3 * 1.3m
2.5m + x = 3.9m
Subtracting 2.5m from both sides, we get:
x = 3.9m - 2.5m = 1.4m
Therefore, the height of the girl is 1.4 meters.
The average height of 2boys and 1girl is 1.3m the height of the two boys are 1metre and 1.5metres respectively what is the height of the girl
