Let the two parallel sides be a and b.
According to the question,
a - b = 8 ... (i)

and 12(a+b)×19=76012(a+b)×19=760
=> a + b = 40×240×2
=> a = b = 80 ... (ii)
From Eqs. (i) and (ii), we get
21 = 88 Therefore, a =882=44882=44
From Eq. (i), we get
a - b = 8
Therefore, b = a - 8 = 44 - 8 = 36 c,
Therefore, a = 44 cm and b - 36 cm
