The length of a diagonal of a square is 37√2 millimeters. find the perimeter of the square

The answer is 148.

Step-by-step explanation:

Because it is a square, the sides are equal. Taking half the square, you have a right triangle with sides that are equal with a hypotenuse of 37√2.

The equation a^2 + b^2 = c^2 applies.

In this case sides a and b are equal, so we can substitute a for b. The following equation applies:

a^2 + a^2 = c^2

2a^2 = c^2

Substitute in the value of C:

2a^2 = (37√2)^2

2a^2 = 1369 * 2

Divide both sides by 2

a^2 = 1369

Take the square root of both sides:

a = 37

Each side is 37 units. The perimeter is 37 * 4 = 148 units.

the answer to this question is "motor unit"

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
