Find the missing dimension of each figure

The area of a parallelogram can be found using the formula [tex]A=bh[/tex].

We know that [tex]A=12[/tex] and [tex]h=5\frac{1}4[/tex], so we can divide 12 by 5¼ to get b.

Let's put 5¼ as an improper fraction to make dividing easier.
5 wholes = 20 fourths. 20 + 1 = 21 fourths.

Dividing by a fraction is the same thing as multiplying by its reciprocal.
To find the reciprocal we flip the numerator and the denominator and get 4/21.

4/21 × 12 = 48/21 which as a simplified mixed number is [tex]\boxed{2\frac{2}7\ ft}[/tex]
