In a rhombus, all the side lengths are $10,$ and one of the angles is equal to $120^\circ. $ Find the area of the rhombus

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: 0.26

i used the calculator on google

b is the correct answer
