The circumference of a pasture is 34 meters, where the width is 4 meters shorter than the long side. Set it up in an equation and figure out how long the sides are.
I think you mean "perimeter," not circumference....
(1/2) Perimeter = W + L .....and L = W + 4...so we have....
17 = W + L
17 = W + [ W + 4 ]
17 =2W + 4 subtract 4 from both sides
13 = 2W divide by 2
6.5 m = W and L = 6.5 + 4 = 10.5 m
