Let a,b,c be the sides of the triangle.
Perimeter 2s = a + b + c
Semi-perimeter, s = (a+b+c)/2
Using Heron's formula:
Area of the triangle A = √s(s−a)(s−b)(s−c)
Now, if the sides are doubled: 2a, 2b, 2c
Let s' be the semi-perimeter.
2s' = 2a + 2b + 2c
s' = a + b + c
or s' = 2s
Area of the triangle, A' = √s′(s′−2a)(s′−2b)(s′−2c)
A' = √(2s)(2s−2a)(2s−2b)(2s−2c)
A' = √24s(s−a)(s−b)(s−c)
A' = 4√s(s−a)(s−b)(s−c)
A' = 4A
A':A = 4:1
Ratio of area of the new triangle and old triangle is 4:1

Pole Star (or ‘Dhruva Tara’) appears stationary in the celestial sphere unlike other stars which seem to be moving.
Pole Star has been one of the most familiar stars to travelers in earlier times to find directions at night. It appears stationary because it is situated in the north direction along the axis of rotation of the earth.

Stars do glow during the day, but we can't see them because of the glare of sunlight. When the sun is up, the blue color in sunlight gets scattered all over the atmosphere, turning the sky the familiar bright blue color. This blue light is much brighter than the faint light coming from the stars, so it prevents us from seeing them.

Metals are a good conductor of electricity which means that they can conduct electricity due to the free moving electrons present in them. Copper is used as wiring as it is a good conductor of electricity. Nonmetals are insulators which means that they’re poor conductors of electricity.
