The height is 9 centimeters

The parallelogram is like rectangle

so, the area is 54 square cm
we use is Working Backward

    N × 6 = 54
the × we will exchange that into ÷
so 6 ÷ 54 = N

N = 9
let's check that
9 × 6 = 54
our answer is correct
so , 9 is the correct answer
1 5 1

The area of the parallelogram is B*h
A=bh
to get the height, derive another equation from the original equation
equation2 is h=A/b; h=54 cm^2/6 cm
h=9 cm (cancellation of unit, so the remaining unit is "cm".

the height of a parallelogram is 9 cm.
