...
The p
erimeter of a square is loo cm. Find its diagonal​

Answer 1

Answer:

35.35 cm

Step-by-step explanation:

here, it  is given that ,

perimeter = 100cm

perimeter of a square = 4 x side

side  = perimeter/4 = 100/4 = 25cm

now, side of square = 25cm. so,

diagonal of a square =  side x $\sqrt{2}$

= 25 x $\sqrt{2}$ = 25$\sqrt{2}$ cm

= 25 x 1.414  (as sqrt(2) = 1.414...)

= 35.35 cm

therefore, 35.35 is the correct answer
