Answer: her interest in 3 years is $45
Step-by-step explanation:
For simple interest, the principal is not compounded. The interest is only on the original capital. The formula for simple interest is expressed as
I = PRT/100
Where
I represents the interest on the principal
P represents the initial amount
R represents the interest rate.
T represents the time in years.
From the information given
P = $300
R = 5%
T = 3 years
I = 300×5×3)/100
I = 4500/100 = 45
It's 3.2 units

The bottom is a square with a side length of 2 ft.
The area of a square is Area = S^2 = 2^2 = 4 square ft. Bottom)
The area of one side ( triangle) = 1/2 x base x height = 1/2 x 2 x 4 = 4 square ft.
There are 4 triangles: 4 x 4 sq. ft. = 16 sq.ft. ( four sides)
Total area = four sides + bottom = 16 + 4 = 20 feet^2
