Find the perimeter of a square with the diagonal 22cm.
perimeter =

P ≅ 62 cm

Step-by-step explanation:

The perimeter of a square of side length s is P = 4s.  Given that the diagonal of this particular square has length 22 cm, we need to find the side length, s, as a preliminary to finding the perimeter, P, of the square.  

The Pythagorean Theorem applies to the diagonal:  the diagonal is the hypotenuse of the square.  Recalling that s is the side length, and that the triangle formed by the diagonal is a right triangle with equal side lengths,

s^2 + s^2 = (22 cm)^2.  Then 2s^2 = 484 cm^2, and s^2 = 242 cm^2.

The side length is thus s = +√(242 cm^2).  This radical cannot be reduced to a more compact form.  

Then the perimeter is P = 4s, or 4·√(242 cm^2).  This comes out to approximately

P ≅ 62 cm

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
