If $55 is put in an account that gets 6% and i add $20 at the end of each year, how much will i have at the end of 10 years?

100+6=106% = 1.06
55x1.06^10= 98.50
98.50 + 20(10) = 258.50

$258.50

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
