let s say one of the length is 7x and another 12x

 

P=(a+b)*2

 

95=(7x+12x)*2

95=38x

x=95/38

 

so:

one of the length is 7x: 95/38*7 = 17.5

 

the other is 13x: 95/38*13 = 32.5

The ratio of a pair of sides of a rectangle is 7 : 12. If the perimeter of the rectangle is 95, what is the length of each side?

 

7 + 12 =19 total ratio

7/19 X 95 =35/2=17.5 the length of the short side

12/19 X 95=60/2=30 the length of the longer side. So that:

2[17.50 + 30]=95 the area of the rectangle.
