The perimeter of a triangular-shaped garden is 58 feet. The longest side of the garden is 18 feet more than the shortest side of the garden. The other side of the garden is 3 times the length of the shortest side of the garden. What is the length of the shortest side of the garden (in feet)?

Step-by-step explanation:

P= perimeter

P=58 feet

shortest side=a

P= (a+18)+3a+a=58

5a+18=58

5a=58-18

5a=40

a=8 ft

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
