Answer:
<h2>total no of markers :36</h2>
in first condition
<h2>no of blue marksers :4</h2>
so probability:

same goes to the second condition
<h2>
<em><u>hope</u></em><em><u> it</u></em><em><u> helps</u></em><em><u> you</u></em><em><u><</u></em><em><u>3</u></em></h2>
6.32 units squared
a^2+b^2=c^2
3^2+b^2=7^2
9+ b^2= 49
-9. -9
b^2 =40
b= 2 square root of 10, -2 square root of 10
b=6.32
4? I'm not sure, since I'm in a rush.
Work:
1. Band 1, 2, 3
2. Band 2, 3, 4
3. Band 3, 4, 1
4. Band 1, 2, 4
2l + 2w = 16
2(l+ w) = 16 Divide both sides by 2
l + w = 16/2
l + w = 8
So for example the length l could be 5 and the width could be 3.
Length could be 5.
I think that is the wrong Chart for the question but the answer is;
