I challenge all the brainlist student any one have capability to solve it.​

Answer 1

Answer:

144×4 =576 ans mark me brainlest

Answer 2

Step-by-step explanation:

we know that diagonals of square are equal

so let length of the one diagonal is=144/2=

72cm

so triangle made by two sides of the square and it's diagonal is right angle and issoscelus triangle

by Pythagoras theorem

(h)2=(p)2+(b)2

we know that p=b

(72)2=(b)2

square root both side

b=72cm

perimeter of square is=4(side)

=4(72)

=288
