Answer:
1. X3, 15x - 10y = 80 15x - 7y = 51
-17y = 29
2. 8 = 1/60 + a. 8 - 1/60 = 7.98333333333
6 = 1/80 + b. 6 - 1/80 = 5.9875
13.9708333333

Step-by-step explanation:
area of hexagon =
*
where a = length of 1 side
this hexagon is made of 6 equivalent triangle
consider ABC triangle
let AC length be x
<em>AB = 2 * AC = 2x = a</em>

Hence a = 8
<u>hence area of hexagon = </u>
<u>*</u>
<u> = </u>
<u> * </u>
<u> = 166.27 m2</u>
