Q:
# An in-ground swimming pool has a length that is three times as long as it is wide, and it has a border around it that measures 200 feet total. How wide is the swimming pool in feet?The perimeter (P) of a rectangle is P=length+length+width+width.

Accepted Solution

A:

Answer: 25 feetStep-by-step explanation:Let w represent the width. Then the length is 3w and the perimeter is ... P = 200 ft = length + length + width + width 200 ft = 3w +3w +w +w 200 ft = 8w . . . . . . . . . . . . . simplify; next, divide by 8 200 ft/8 = w = 25 ftThe width of the swimming pool is 25 feet.
