Answer:
88 trucks
Step-by-step explanation:
Ratio of cars : vehicles = 5:13
Hence, the ratio of trucks : vehicles = 8:13
143/13 = 11
If the number of vehicles is 143,
we have to multiply both sides of the ratio by 11:
8*11 : 13* 11
88 : 143
Hence, there are 88 trucks for every 143 vehicles.

For this case we have the following data:
Area of the rectangle, 
Relationship of the sides 5: 3
By definition, the area of a rectangle is given by:

Where
- b: it is the side of least length.
If the sides have a 5: 3 ratio, it means:


Substituting in the formula of the area, we have:


Clearing b:

9-1a/2 = 5+4a
-5 -5
4-1a/2 = 4a
+1a/2 +1a/2
4 = 9a/2
*2 *2
8 = 9a
/9 /9
8/9 = a
