For this case we have that the area of the kite is given by the area of two triangles, the triangles share the same base of 3 + 3 = 6 meters and one has height of 2m and the other height of 4m.
So, the total area is given by:

Thus, the area of the kite is

Data:
A = ₹117 000
P = ₹90 000
r = 6 % = 0.06
n = 1
Calculations:


Divide each side by 90 0000

Take the logarithm of each side
log1.3 = tlog1.06
0.1139 = 0.025 31t
Divide each side by 0.025 31
t = 4.50 yr
You can buy your magic carpet in 4.50 yr.
2% of 1000 is 20 and 5% of 800 is 40 so account b earns more
