We are given two quadrilaterals ABCD and JKLM which are similar. For similar quadrilaterals, the sides of the quadrilateral are congruent. We use the formula below
[tex]\frac{JM}{AD}=\frac{KL}{BC}[/tex]
Where JM=3.2, AD=4, KL=x, BC=7
We then substitute the necessary parameters into the formula above.
[tex]\begin{gathered} \frac{3.2}{4}=\frac{x}{7} \\ we\text{ crossmultiply} \\ 4x=7\times3.2 \\ 4x=22.4 \\ \text{Divide both sides by 4} \\ \frac{4x}{4}=\frac{22.4}{4} \\ x=5.6 \end{gathered}[/tex]
The length of x is
ANSWER: x=5.6
