Parallelogram Law:
If two vector acting on a particle at the same time are represented in magnitude and directed in two adjacent sides od paralleloram drawn from a pint  this resultant vector are represented by.:
a^2 + b^2 = (a+b) (a+b) = d1*d2

Dear Student,
 Here ,According to Parallelogram law ,
Parallelogram Law:
If two vector acting on a particle at the same time are represented in magnitude and directed in two adjacent sides od paralleloram drawn from a pint  this resultant vector are represented by.
a^2 + b^2 = (a+b) (a+b) = d1*d2
i.e.;a^2=(a+b),b^2=(a+b)
Hope it helps you
