Question

find the side and perimeter of a square with diagonal of 200 cm​

Answer 1

Answer:

Let the side of a square be'a'

diagonal of a square = a*√2

according to the question,

a*√2=200

a=200/√2

a=200*√2/√2*√2

a= 200√2/2

a=100√2

side of a square is 100√2 cm

perimeter of a square = 4*a

= 4*100√2 cm

=400√2

Perimeter of a square is 400√2 cm

Answer 2

Answer:

Let the side of a square be'a'

diagonal of a square = a*√2

according to the question,

a=200/√2

a=200*√2/√2*√2

a= 200√2/2

a=100√2

side of a square is 100√2 cm

perimeter of a square = 4*a

= 4*100√2 cm

=400√2

Perimeter of a square is 400√2 cm
