The earth receives energy from the Sun in the form of radiation . The Earth reflects about 30% of the incoming solar radiation. In polar areas, solar radiation strikes earth at a low angle. The more acute the angle at which the sunlight strikes, the more atmosphere that sunlight must pass through.
Let the length of the rectangle be 3x and breadth be 1x Given, perimeter = 96 m 2(l + b) = 96 (or) l + b = 48 (or) 3x + 1x = 48 (or) x = 12 m Now, Length of the rectangle = 12 x 3 = 36 m
