The area of a shape is the amount of space it occupies

The complete statement is: First, break the irregular polygon into shapes whose area you can find using familiar formulas. The sum of these areas is the area of the polygon.

<h3>How to determine the area of an irregular polygon</h3>

An irregular polygon contains several familiar shapes.

So, the first thing to do is to break the polygon into smaller shapes

Then calculate the areas of these shapes

Lastly, add the areas of the shapes to get the area of the irregular polygon

Hence, the area of an irregular polygon is the sum of the areas of the shapes that make up the irregular polygon

Rajan needs 1 liter of 15% hydrochloric acid solution for an experiment. He checks his storage cabinet, but he only has a 5-lite

Delvig [45]

Answer:

<em>0.75</em><em> liters of 5% hydrochloric acid solution </em>
<em>0.25</em><em> liters of 45% hydrochloric acid solution.</em>

Step-by-step explanation:

Let us assume that, x liters of the 5% hydrochloric acid and y liters of the 45% hydrochloric acid solutions are combined.

As Rajan need total of 1 liter of solution, so

$x+y=1$

i.e $x=1-y$ --------------------1

As Rajan needs 5% hydrochloric acid and 45% hydrochloric acid to make a 1 liter batch of 15% hydrochloric acid, hence acid content of the mixture of two acids will be same as of the final one, so

$0.05x+0.45y=1\times 0.15$
