40.249 rounded would be 40.2
Length of one side times how many sides there are .P= S x N
The answer Is: C because it’s a line that passss through the two points in the table
26/25 aka 1 1/25
explanation
the first drawing has 11 shaded out of 25
11/25
The second one has three out of 5
5 times 5 is 25
3 times 5 is 15
there fore it would have 15 shaded out of 25
15/25
and 15/25 plus 11/25 is 26/25
X+y=90
x<2y
x+y< 3y
but x+y=90
90<3y
⇒ y>30
for example y=31, then x= 59
y=32, x= 58
.............................................
y=40, x=50
