Question

the ratio of the length to the width of a rectangle is 10:6. If the perimeter of the rectangle is 160 meters, find the measure of the width.

Answer 1

Another way to do the same problem is to let x be the proportion constant...

10x + 6x = 160

16x = 160

x = 10

Then both lengths are 10*10 = 100, which means each length is 50

Both widths are 6*10=60, which means each width is 30
