I am assuming this is a trapezoid.
The area of a trapezoid is : A=(B1+B2)H/2
Plug in the numbers to get:
18=(6+B2)*2/2
18=6+B2
18-6=6-6+B2
B2=12

Answer:

12 units

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.
