Answer:
748.23 in²
Step-by-step explanation:
<u>Area of a Regular Polygon</u>

where:
- n = number of sides
- l = length of one side
- a = apothem
Given:
- n = 6
- l = 101.8 ÷ 6
- a = 14.7
Substituting the given values into the formula and solving for A:




Therefore, the area of the hexagon is 748.23 in²
Answer:
Step-by-step explanation:
a = 2i + 3j + zk
b = xi + 1j + 4k
Given a X b = 6i -14j +5k
a X b = | i j k|
|2 3 z|
|x 1 4|
a X b = i(12-z) - j(8 - xz) + k(2-3x) = 6i -14j +5k
equate the coefficients of i , j and k
12- z = 6; implies z = 6
8 - xz = -14 implies 8 - 6x = -14
2-3x = 5 implies 2 - 3x = 5 implies x = -1
