Question

find the diagonal of square whose perimeter is 60 CM​

Answer 1

Step-by-step explanation:

Given that

Perimeter of a square = 60cm

4a = 60cm

a = 60/4

a = 15cm

Diagonal of a a square = √2 × a

as we got the value of "a" substitute it

= √2 × 15

= 15 √2 cm

hope it helps u......❣️

Answer 2

Step-by-step explanation:

perimeter of square =4×side

therefore,side=60/4=15

now {diagonal}2 = [15]2+[15]2=225+225=450

therefore ,diagonal=15√2
