Area should be 4*4 + 0.5*4*1 = 18

We have a trapezoid with height OP and bases OR and PQ
Length of PQ
∆ OPQ is right isosceles with equal sides OP and PQ
--The angle at P is 90°
PQ || OR. The two segments are cut by traversal OP. Same-side interior angles sum to 180.
∠ POR = 90, hence the angle at P is also 90
-- ∠ PQO = 45. Parallel lines are cut by the traversal OQ, and ∠ QOR = 45. As an alternate interior angle, ∠ PQO also = 45°
-- ∠ POQ is 45: the right angle at vertex O has one angle marked as 45°; 90 - 45 = 45 = ∠ POQ
--OP = PQ: sides opposite equal angles of a triangle are equal
--OP = 4 = PQ, which is one base of the trapezoid
Height, other base, and area
The height of the trapezoid is OP = 4 (Height is perpendicular to base; OP is perpendicular to OR and PQ.)
The other base is OR = 5
Area of trapezoid: \(\frac{(base_1 + base_2)}{2} * h\)
\((\frac{4 + 5}{2}) * 4 = (4.5 * 4)=\\
18\)
Answer C
