Perimeter of a square = 4 x side
4x + 20 = side x 4
side = 4x + 20 / 4
side = 4 ( x + 5 ) / 4
∴side = x + 5 cm.
Now,
Diagonal of a square = √2 * side
Diagonal = √2 * ( x + 5 ) cm
4x + 20 = side x 4
side = 4x + 20 / 4
side = 4 ( x + 5 ) / 4
∴side = x + 5 cm.
Now,
Diagonal of a square = √2 * side
Diagonal = √2 * ( x + 5 ) cm
