Question

the perimeter of square is 144 cm​

Answer 1

Answer:

Perimeter = 4s where s is the length of one side of the square.

P=144 = 4s

s =144/4 = 36

The square has width and length of 36 cm.

A 45° 45° 90° right triangle is formed on both sides of the diagonal in a square, with its legs being the sides of the Square. The diagonal of the square forms the hypotenuse of this right triangle. And in such a triangle the hypotenuse is (the square root of 2) times the leg length, (in this case, 36).

Therefore the length of the diagonal of the square with 144 cm perimeter is 362–√ cm
