If they share the money in ratio 7:n
And Ann had 28%
Thus unit ratio will be 28/7 = 4
Since Bill had 100 - 28 = 72%
Bill ratio will be 72/4 = 18
7:n will be 7:18
Thus the value of n is 18
I'm not really sure but a it could be 2
Answer:
I am not sure, I think it's 45
Step-by-step explanation:
The figure is a trapezium and area of a trapezium is 1/2 h ( sum of parallel sides)
Area = 1/2 x 5(there are 5 squares) {7 +10 + sum of the 2 halves => 1}
= 1/2 x5(7+10+1)
= 1/2 x 5 x 18
= 45
