Question

The area of the rhombus is 20 square inches. What is x?

5 in.
60 in.
4 in.
6 2/3 in.

Answer 1

1/3 ft. = 4 inches

`x * 4 = 20 {inches}^(2) \\ x = 20 / 4 \\ x = 5`
The answer is 5 inches.

Hope this helps.

Answer 2

Answer: First option is correct.

Explanation:

Since we have given that

Area of the rhombus = 20 sq. inches

Height of rhombus =
`(1)/(3)\ ft=(1)/(3)* 12\ inches=4\ inches`

Base of rhombus = x inches

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

`Area=base* height\\\\20=x* 4\\\\(20)/(4)=x\\\\5\ inches=x`

Hence, First option is correct.
