fencing a field

Postby Motherof8 on Tue Aug 30, 2011 1:56 pm

It takes 184 rods of fencing to enclose a rectangular field containing 13 acres. Find the dimensions of the field. (1 acre = 160 sq. rods). I multiiplied 160 x 13 and got 2,080 sq. rods. It seems that therre is more field than fencing to cover it. ( I noticed it said 184 rods instead of square rods.)

'rods' would be like 'yards' - distance
'sq rods' would be like 'sq yds' - area
do area & perim eqns
2L+2w=184
Lw=2080
solve for L & w
