The area of the polygon is:
A = 2 × 12 + 14(12+2) + 3(12 + 2 + 3)
A = 2 × 12 + 14 × 14 + 3 × 17
A = 24 + 196 + 51
A = 220 + 51
A = 271 cm²
Answer:
B. 271 square units
Explanation:
The area is the sum of 3 rectangles areas
step 1 12 * 19 = 228
step 2 3 * 3 = 9
step 3 2 * 17 = 34
Now, we add all the answers we got to get the area.
= 228 + 34 + 9 = 271 square units
