+709 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?
+2499 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.
