B) First put the total number of students in the bottom and part of the students on top. Then the 100. So the equation should look like this. 66/300=x/100
Using Pythagoras’ theorem a2 + b2 = c2 you can find out the third (longest) side. (6x6) + (8x8) = 100 (the square root of 100 is 10) so ur final sum is 6+8+10 = 24 mm
