pass the line i drew and then you'll have a square (think about why its a square if you got those 90 angles). so its 4^2=16.

the other shape is a trapeze so if you know the area formula its (2+4)×4/2 = 12.

12+16 = 28.

if you don't know the trapeze formula you can do a square minus the triangular with bases of 4 and 2

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

360/29
