Step-by-step explanation:
The formula for the area of a trapezoid is
a + b
-------- x h (Where a and b are bases)
2
The bases of the trapezium are 6cm and 6cm while the height is AB = 12cm.
So, if you substitute the values, you get
= 6 + 6
-------- x 12
2
= 12
-------- x 12
2
= 6 x 12
= 72 cm²
Therefore, your answer is 72cm².
Hope this helps...
