What is the area of this polygon??

(NO LINK PLS <3)

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

Ineed in figuring out this problem.
