Answer:

The length of each side of the larger square is 8 centimeter.

Step-by-step explanation:

Given:

The combined area of two squares is 80 square centimeters. Each side of one square is twice as long as a side of the other square.

Now, to find the length of each side of the larger square.

Let [tex]s[/tex] be the length of the smaller square.

So, the length of the larger square = [tex]2s.[/tex]

Now, we find the areas of the square by putting formula:

The area of smaller square = length²  [tex]=s^2.[/tex]

The area of larger square = (length)²  [tex]=(2s)^2=4s^2.[/tex]

As, given:

The combined area of two squares is 80 square centimeters.

According to question:

[tex]s^2+4s^2=80\\5s^2=80[/tex]

So, dividing both sides by 5 we get:

[tex]s^2=16[/tex]

Using square root on both sides we get:

[tex]s=4\ centimeter.[/tex]

And, to get the  length of each side of the larger square we substitute the value of [tex]s[/tex]:

[tex]2s=2\times 4=8\ centimeter.[/tex]

The length of larger square = 8 centimeter

Therefore, the length of each side of the larger square is 8 centimeter.
