a = 1/2*b*h
h = 1/2*b*1/a
h = 1/2 * 8 - 4√3/ 9 + 4√3
h = 1/2 * 8 - 4√3/ 9 + 4√3 * 9 - 4√3/ 9 - 4√3
h = 1/2 * 72 - 32√3 - 36√3 + 48 / 81 - 48
h = 1/2 * 120 - 68√3 / 33
h = 1/2 * 2( 60 - 34√3) / 33
h = 60 - 34√3 / 33
= a+ b√3
= 60/33 - 34/33
= 20/11 - 34/33
therefore , a = 20/11
b = 34/33
hope it helps you.....
