Answer 2

Step-by-step explanation:

ABCD is a square

It's diagonal intersect at 0

it's makes 4 triangle all triangles are of same measure since it is a square

so if area of 1 triangle (i.e. ∆OAB) is 4cm^2 so the are of whole square is 4×4=16cm^2

so if the area is 16cm^2 then side would be

(s=one side, A=area)

= s×s = A

= s×s = 16

= s = √16

= s = 4

one side of triangle = 4cm
