Each team needs two people for a 3-legged race. Therefore, the number of orders (combinations) of 2 people at a time from 8 is ₈C₂ = 8!/(2!6!) = (8*7*6!)/(2*6!) = (8*7)/2 = 56/2 = 28
Let breadth(b) of rectangular be x Then length(l) = 5x + 1 We have : perimeter(p) =2(l+b) Or, p = 2 (5x+1+x) p = 2 (6x+ 1) p = 12x + 2 Given that p= 98 m 98=12x+2 i.e. x= 8 So breadth b= 8m and length l =5*8+1= 41m
I think you divide 5/9 divided by 2/3. 5/9 divided by 2/3=4/3 simplified=2/3. Just know I'm terrible at math so this could be like totally off the hook crazy and wrong.
