Find the missing dimension of each figure
parallelogram: h= 5 1/4 ft; a= 12 ft 2

The area of a parallelogram can be found using the formula .

We know that and , 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

what exact part do you need with? or is it the hwole thing i shall you with
