i need help! please show how you got the answer

Answer:
x = 9 3/13 cm
Step-by-step explanation:
area = (length)( width)
20 cm² = (x)(2 1/6 cm)
x = 20 cm²/2 1/6 cm = (20)/(13/6) = (20)(6/13)
x = 9 3/13 cm
Area = 20 cm²
Breadth = 13÷6
Length = x
Area = l × b
20 = l × 13÷6
Therefore: l = 20 × 6 ÷ 13
l = 9 3/13
Therefore x in the figure = 9 3/13
