The problem is stating that there is a a ratio of 2:3 of pine to maples trees. Thus the total number of pine trees planted will be given by: total ratio=2+3=5 thus the number of pines will be: 2/5×300 =120 pines
This problem is stating that there is a 2 to 3 ratio of pine trees to maple trees. This is also saying that for every 5 trees, 2 will be pine and 3 will be maple. We divide 300 by five to get 60. One fifth of the total amount of trees is 60. Since we know2/5 trees are pine and 3/5 trees are maple, we can multiply 60 by 2 to get an answer of 120 pine trees, by default we have 180 maple.
It is ten units, as the two sides are of 6 and 8 so you must square them both, add them together (which gives you 100) and then square root that, which gives you 10
