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. What is the length of each side of the larger square?

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

So, the side of the larger square is

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

The area of smaller square = (side)²  

The area of larger square = (side)²  

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

According to question:

Dividing both sides by 5 we get:

Using square root on both sides we get:

Now, to get the  length of each side of the larger square we put the value of :

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