B1 = 6 , h = 2 , and a = 18 . what is b2?

12 units

Step-by-step explanation:

Given that the trapezium has base 1 = 6, height = 2 and area = 18

Formula for area of a trapezium

=1/2 h(b1+b2),

where h = height of trapezium

b1 = base length of one parallel side

b2 = base length of second parallel side

Of these we know everything except b2.

Substitute for known values

18=1/2 (2)(6+b2)

b2 =12

Thus second base for the trapezium is 12 units.
