1. Perimeter
22a + 2(6a + 8) -4 = p
[I got 22a from 12a + 10a]
2. If p = 250, what is a?
22a + 2(6a + 8) - 4 = 250
Distributive property
22a + 12a + 16 - 4 = 250
Add like terms
34a + 12 = 250
Subtract 12 by both sides
34a = 238
Divide 34 by both sides
a = 7

Answer:
10rupee notes are 11
20rupee notes are 22
Step-by-step explanation:
Let 10-rupee note be x
20-rupee note will be x + 11
The equation will be
10x + 20(x + 11) = 550
10x + 20x + 220 = 550
30x = 330
x = 330/30 = 11 = 10rupee notes
y = 11+11 = 22 = 20rupee notes
