25 = 5.2 + 8 + x
5.2 + 8 = 13.2
25 = 13.2 + x
25 - 13.2 = 11.8
11.8 = x
The unknown side is 11.8 ft.
John is 31 and Jenny is 26
To calculate the area you would do L*w=a² and that is how much ft of rug you will need
You can cross multiply. 36 times 3 is 108. then divide 108/18x which gives you 6.
6(54 + 48). I'm not sure what this question is asking but the GCF is 6. That is all I did pretty much.
