Step-by-step explanation:
Refer to the given attachment for the required polygon.
We see that we have formed a right-angled triangle ABO, whose sides are AB, BO and OA.
Here AB is the height and BO is the base of the triangle ABO.
Also, AB = 4 units and BO = 5 units
Therefore the area of triangle ABO
= 1/2 * base * height [this is the formula of area for right-angled triangle]
= 1/2 * BO * AB
= 1/2 * 5 * 4 square units
= 5 * 2 square units
= 10 square units
Final answer:
The area of the polygon is 10 square units.
