The exponential growth formula can find the interest rate.

y - tolat value (P +I) (216)
a - principal (200)
r- rate (unkown)
x - time in years (2 yrs)
Substitute known values

divide both sides by 200

take the square root of both sides

subtract 1 on both sides
r = 0.0392 or 3.92%

it helps you because you can divide the bottom to the top or vice versa or you can divide x and y

Answer: 11/20</h3>
=====================================================
Work Shown:
x = unknown horizontal length
1/5 = 0.2
Perimeter = 2*(width + length)
P = 2*(0.2 + x)
P = 0.4 + 2x
Set this equal to the given perimeter of 1 & 1/2 = 1.5 and solve for x
0.4 + 2x = 1.5
2x = 1.5-0.4
2x = 1.1
x = (1.1)/2
x = 0.55
x = 55/100
x = (5*11)/(5*20)
x = 11/20
