**Steve**, Thursday, September 13, 2012 at 10:47aml/b = 7/4

l = b+746.1

so, since l = 7/4 b,

7/4 b = b+746.1

3/4 b = 746.1

b = 994.8

so, l = 1740.9

check: 1740.9/994.8 = 1.75 = 7/4

**Reiny**, Thursday, September 13, 2012 at 10:51aml:b = 7:4

l/b=7/4

4l=7b

but l = b+746.1

4(b+746.1) = 7b

2984.4 = 3b

b = 994.8

l = 994.8 + 746.1 = 1740.9

perimeter = 2l + 2b = .....
