Answer:

30 units

Step-by-step explanation:

We are given that The ratio of the areas of two parallelograms is 4:9.

So, ratio of sides of parallelograms : \sqrt{\frac{4}{9}} = \frac{2}{3}

So, sides ratios is 2:3

We are given that The perimeter of the smaller parallelogram is 20 units.

Let the perimeter of the bigger parallelogram be x

So, \frac{2}{3}=\frac{20}{x}

x=\frac{3}{2} \times 20

x=30

Thus the perimeter of the larger parallelogram is 30 units

With a ratio, you should think of it in terms of a pie of sorts. In this example, the pie has 13 pieces, 9 of which consist of the perimeter of the large parallelogram and 4 of which consist of the perimeter of the smaller parallelogram. If we know that those 4 pieces of pie and equal to 20 units, then we would divide 20 by 4 to find the value of a single piece. 20/4=5 so a single piece of pie has a value of 5 units. We would then multiply 9 by 5 to find the value equivalent of the 9 pieces of pie. 9(5)=45. Therefore, the perimeter of the larger parallelogram is 45.
