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

Step-by-step 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

A parallelogram has a perimeter of 42 meters. Two sides are each 19.8 meters long. What is the length of the other two sides?
ValentinkaMS [17]
We first add both 19.8 by 19.8 and therefore, that would give us 39.6.

42 - 39.6 = 2.4.

2.4 ÷ 2 = 1.2

1.2 would be the length of each sides.
