Question

Square ABCD have length 300. AB=BC=CD=AD then find its diagonal.

Answer 1

Step-by-step explanation:

Side of square=300 unit

Since it is square, AB=BC=CD=AD.

Construct a diagonal say AC(you may take BD as both diagonal of square are equal).

Then using Pythagoras Theorem,

AB²+BC²=AC²

=>300²+300²=AC²

=>AC²=90000+90000

=>AC²=180000

=>AC²=2×9×10000

=>AC=300×(Root2)

ALITER

d=(root2)×s

d is diagonal length

s is side of square
