1.....AREA OF SQUARE = SIDE * SIDE...

SO AREA = 12*12

AREA = 144CM2

2....DIAGONAL OF A SQUARE=√2*SIDE..

SO DIAGONAL= √2*12

SO DIAGONAL= 12√2 CM ...

shreya32457: hey...very easy question

js3842029gmailcom: than solve it di

shreya32457: diagonal is 6√2......means diagonal is √2*side

shreya32457: 6√2= √2*side

shreya32457: side= 6√2/√2.......=6

shreya32457: perimeter = 4*side.......4*6= 24cm

shreya32457: area = side2= 6*6=36sqcm

shreya32457: is it clear

Side = 12

Area = side x side = 12 x 12 = 144cm²

Perimetre = side x 4 = 12 x 4 = 48cm

Diagonal =

a² + b² = c²

12² + 12² = 144 + 144 = 288

C² = 288

c = √288 = 12√2cm
