Answer:

<h2>Width = 7.6 ft.</h2><h2>Length = 12.7 ft.</h2>

Step-by-step explanation:

Perimeter of a rectangle (P) = 2L + 2W

where

P = 40.6 ft.

L = 2W-2.5

plugin values into the formula:

40.6 = 2(2W-2.5) + 2W

40.6 = 4W - 5 + 2W

40.6 + 5 = 6W

W = 45.6 / 6

W = 7.6 ft.

L = 2W-2.5

L = 2(7.6) - 2.5

L = 12.7 ft.

proof:

P = 2(12.7) + 2(7.6)

P = 40.6 ft.

The easiest way to do this is the following: if the amount increases with 7% each year, it means that you have to multiply the £400 by 1,07. Then you multiply that answer by 1,07 and one time again. The final answer is 490,0172
