[tex]x \times 4 = 20 {inches}^{2} \\ x = 20 \div 4 \\ x = 5[/tex]
The answer is 5 inches.

Hope this helps.

Answer:  First option is correct.

Step-by-step explanation:

Since we have given that

Area of the rhombus = 20 sq. inches

Height of rhombus = [tex]\frac{1}{3}\ ft=\frac{1}{3}\times 12\ inches=4\ inches[/tex]

Base of rhombus = x inches

As we know the formula for "Area of rhombus":

[tex]Area=base\times height\\\\20=x\times 4\\\\\dfrac{20}{4}=x\\\\5\ inches=x[/tex]

Hence, First option is correct.
