Step-by-step explanation:
The perimeters of the similar figures have the same ratio as the sides.
ratio of perimeters = 
ratio of areas = 11² : 6² , that is 121 : 36
ratio of areas = 
You find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m
<h3>Solution :</h3>
Distance between first tree and last tree is 140m .
And distance between each tree (d) = 5 m
let's solve for number of trees (n) :





hence, total number of trees = 29.
