Width = 13cm

Length = 16cm

<u>Explanation:</u>

Let width = b,

So, length = b+3

Perimeter of rectangle = 2x(length + width)

According to the question,

58cm = 2X(b+3 + b)\\58cm = 2X(2b+3)\\29cm = 2b+3\\ 26cm = 2b\\b = 13cm

Hence,

Width = 13cm

Length = 16cm

Answer: 2years, 5 months

Step-by-step explanation:

Principal, P = $6000

Rate, R = 3%

Interest, I = $450

Time, T =?

Simple Interest, I = P x T x R/ 100

making T, subject of formula

T = 100 x I/ P x T

Substituting the values into the equation,

T = 100 x 450/ 6000 x 3

T = 45000/ 18000

T = 2.5years = 2years, 5 months
