Answer:
Explanation:
Water scarcity already affects every continent. Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of physical scarcity, and 500 million people are approaching this situation. Another 1.6 billion people, or almost one quarter of the world's population, face economic water shortage (where countries lack the necessary infrastructure to take water from rivers and aquifers).
Water scarcity is among the main problems to be faced by many societies and the World in the XXIst century. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water.
Water scarcity is both a natural and a human-made phenomenon. There is enough freshwater on the planet for seven billion people but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed.

> Diagonals of a Rhombus Bisects the Angles at the Vertex
=> For a vertice holding an angle 120°, the Bisected Angle = 60°
Further, the Angle at the Second Vertice = 60°
Hence, we have an Equilateral Triangle with two sides as 10cm and the third - a diagonal
=> By definition of an Equilateral Triangle, Diagonal = 10cm
