Answer:
A
Explanation:
the area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the height )
let base be represented by b and height by h , then b = 2h
given A = 72 and substituting into the formula
bh = 72 , that is
2h × h = 72
2h² = 72 ( divide both sides by 2 )
h² = 36 ( take square root of both sides )
=
, that is
h = 6
