Area of square=side×side=5625 m^2

side=square root 5625

side=75 m

when we cut the square in the form of two triangle,we get

1/2×h×b + 1/2×h×b=5625 m^2

we put pythogoes thermos

because square all angle is 90°

we have,

p=75 m

b=75 m

h= we find hypothesis

we putting the formula

h^2= p^2 + b^2

h^2= (75)^2 + (75)^2

h^2= 5625 + 5625

h^2= 11250

h= square root 11250

h= 106.066

the length of the diagonal of the square is 106.066 m.
