we are given that ,
The combined area of two squares is 17 square meters.
Area of square=
![(side)^2](https://img.qammunity.org/2019/formulas/mathematics/college/zk46f7edwted19v74m78y91weanvwh0ajc.png)
Let the side length of smaller square be x
The size of the larger Square are four times as long as the size of the smaller square
![Area \ of \ smaller \ square \ =x^2](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ltd8p4t1riyxo6x0kpc4rwlhow8d1lifdl.png)
So Area of larger square=
![4x^2](https://img.qammunity.org/2019/formulas/mathematics/middle-school/sx8xbc4aq54cmw3s74imkohg5mccl5fl7r.png)
The combined Area is 17 square meter.
![x^2+4x^2=17\\\\5x^2=17\\\\x=\sqrt{(17)/(5)}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/7mm72rivwnecxc0dzl9hvy6uob5z39h110.png)
Hence the smaller square has the side length=
![\sqrt{(17)/(5)}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/4n78awjfw4gb4xzbulcxn9lzds5f0uf0gj.png)
So the larger square has side length=
![2\sqrt{(17)/(5)}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/9v0abtlqm6slsi2egw30plhi0npdp7n0a1.png)
