The area of a square photo is 9 square inches how long is each side of the photo

1 answer:

3 0

Let the side of each side of photo is a inch.

So area of photo = (side)^2 = $a^2$

But as given area of photo is 9 square inch.

So $a^2 = 9$

$a = \sqrt{9}$
$= 3$

So side of photo is 3 inch.

<h3>Constant of Proportionality</h3>

The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship. Other names for the constant of proportionality include the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.

In this question, the constant of proportionality is that value that doesn't change or represents the number of players while x represented the number of games they played.

The constant of proportionality can be solved mathematically as

$y = 11x\\x = 2\\22 = 11(2)\\22 = 22\\$
