Answer:

the diagonal will make a right angled triangle with the two sides of the square

let the measure of one side bex

then using pythagoras theorem we get,

x^2+x^2=29^2

x^2+x^2= 841

841/2=x^2

420.5=x^2

if x is the side thenzx^2 is the area of square

threfore area of square=420.5

hope it helps you psl mark it brainlist

 29 = \sqrt{2 {a}^{2} }  \\  {29}^{2}  = 2 {a}^{2}  \\ 841 = 2 {a}^{2}  \\ 410.2 =  {a}^{2}  \\ 20.26

HOPE THIS HELPS
