Step-by-step explanation:
A regular polygon is a shape with equal sides and angles. Because of this, we can write the following equation to set two sides equal to each other:
Solving, we will get a in terms of b:
Now we can substitute a for (b+3) into our equation:
Therefore, the length of each side of this polygon is .
Since the perimeter of the polygon consists of all five sides, the perimeter is:
£7200
In first year depreciates by 20%, that is it is worth 80% of it's original value
80% = = 0.8
value after 1 year = 0.8 × £10000 = £8000
In the second year it depreciates by 10% of it's value, that is it is worth 90% of it's value at the end of the first year.
90% = = 0.9
value after 2 years = 0.9 × £8000 = £7200
