Answer:
[tex] x = 2 [/tex]
Step-by-step explanation:
Figure B = 2½ the size of figure A
One side of figure B is given as 5, therefore, 5 = 2½ of x in figure A.
Thus, [tex] 5 = 2\frac{1}{2}*x [/tex]
Solve for x
[tex] 5 = \frac{5}{2}*x [/tex]
[tex] 5*2 = \frac{5x}{2}*2 [/tex]
[tex] 10 = 5x [/tex]
[tex] \frac{10}{5} = \frac{5x}{5} [/tex]
[tex] 2 = x [/tex]
[tex] x = 2 [/tex]
