<PRE><B>Question 278450</B>
A rectangular field 15 feet wide is enclosed by a fence.
 If the area of the field is 360 square feet, how many feet of fencing
 are used to enclose the field?
:
Find the length of the field, L * W = 360; therefore
L = {{{360/15}}}
L = 24 ft is the length
;
Find the perimeter to find the amt of fence required
P = 2L + 2W
P = 2(24) + 2(15)
P = 48 + 30
P = 78 ft of fence</PRE>
