Answer:
(d) A = 18 units²
Step-by-step explanation:
Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...
A = 1/2bh
Then the sum of the areas of the two triangles is ...
A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18
The area of the polygon is 18 square units.
