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 the side of the smaller square be [tex]x.[/tex]

So, the side of the larger square is [tex]2x.[/tex]

Now, getting the areas of the square we put formula:

The area of smaller square = (side)²  [tex]=x^2.[/tex]

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

As, given the combined area of two squares is 80 square centimeters.

According to question:

[tex]x^2+4x^2=80[/tex]

[tex]5x^2=80[/tex]

Dividing both sides by 5 we get:

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

Using square root on both sides we get:

[tex]x=4.[/tex]

Now, to get the  length of each side of the larger square we put the value of [tex]x[/tex]:

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

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