Answer:

x = 9

Step-by-step explanation:

Assuming the rectangles are similar

13           x

------ = ---------

130         90

Using cross products

13*90 = 130*x

Divide each side by 130

13*90/130 = x

x = 9

Answer:

x/90 = 13/130(you can simplify this btw)

x90       x90

X = 9

Make both of them ratios

X to 90 and pick another random one 13 to 130.

Make sure to make them equal to eachother then just solve for x.

You can also compare it to 9 to 90

It would still work:

x/90 = 9/90

x90      x90

X = 9, x would also equal 9
