Whats the length of the patio?
nikdorinn [45]

Answer:

Length = 20 feet; x = 14

Step-by-step explanation:

Parameter = width + length + width + length

64 feet = 12 feet × 2 + (x + 6) feet × 2

64 = 24 + (x + 6) × 2

64 - 24 = (x + 6) × 2

40 = (x + 6) × 2

40 ÷ 2 = x + 6

20 = x + 6

20 = length

20 - 6 = x

14 = x
