Since SQ is the diagonal of the square PQRS. Area of triangle SRQ will be half of PQRS. Now Triangle TUR is 1/4 of the area of SRQ. Hence the triangle TUR will be 1/8 of the area of the triangle PQRS.

B is the answer.

ST=TQ tells us that T is the center of the square.
SU=RU tells us that U is the midpoint of SR.

This translates to TUR being \(\frac{1}{2}\) of TSR
TSR is \(\frac{1}{2}\) of SQR

SQR is half your square.

There can be 8 equal segments of area TUR in the square, therefore TUR is \(\frac{1}{8}\) the area of the square.
