- Lena's Method: 280
- Jackson's Method: 280
Step-by-step explanation:
Lena's Method:
- 8 + 12 = 20
- Plug 20 in: 14(20)
- 14(20) = 14 × 20 = 280
Jackson's Method:
- 14 × 8 = 112
- 14 × 12 = 168
- Re-write the expression: 112 + 168
- 112 + 168 = 280

Answer:
- draw lines center to vertex
- 43.5 square inches
- 261 square inches
Step-by-step explanation:
<u>Part A</u>:
The area can be decomposed into triangles by drawing a line from the center to each vertex of the hexagon.
__
<u>Part B</u>:
The area of each triangle is given by the triangle area formula:
A = (1/2)bh
A = (1/2)(10 in)(8.7 in) = 43.5 in²
__
<u>Part C</u>:
The area of the table top is 6 times the area of one triangle:
surface area = 6(43.5 in²) = 261 in²
