11) 1000000
12) 3430
hopefully these are right
Step-by-step explanation:
You can use the fractions 3/18 and 5/12.
Hope this helps :)
We know that
<span>The nine radii of a regular Nonagon divides into 9 congruent isosceles triangles
</span>therefore
[the area of <span>a regular nonagon]=9*[area of isosceles triangle]
</span>[area of isosceles triangle]=b*h/2------> 15*20.6/2----> 154.5 cm²
so
[the area of a regular nonagon]=9*[154.5]------> 1390.5 cm²
the answer is
1390.5 cm²
Odd integers are 2 apart from each other (in between them is an even number)
x and x+2 is answer
