Width = 20 feet
length = 2(20) = 40 feet
then the perimeter equals 2width+ 2length = 2(20)+ 2(40) = 40+80 = 120 feet
The amount invested in both the 9% and 12% account are :
Let :
Amount invested in 9% account = p
Amount invested in 12% account = 14000 - p
Total interest earned = 1350
Recall :
- Simple interest = Principal × rate × time
- Interest from 9% account + interest from 12% account = 1350
(p × 9% × 1) + ((1400 - p) × 12% × 1) = 1350
0.09p + 1680 - 0.12p = 1350
-0.03p = 1350 - 1680
-0.03p = - 330
p = 330 / 0.03
p = 11000
Hence,
Amount invested in 9% account = 11,000
Amount invested in 12% account = 14000 - 11000 = 3000
