Question

find the side of perimeter of a square diagonal is 10 cm..​

Answer 1

Answer:

Side of Square = 5√2 cm

Perimeter of Square = 20√2cm

Step-by-step explanation:

Diagonal of a square = 2a

10 = √2×Side

10/√2 = Side

(10/√2) × (√2/√2) = Side

Side = 10√2 / 2

Side = 5√2 cm

a(Side) = 5√2 cm

Perimeter of Square = 4a

= 4 × (5√2)

= 20√2cm
