What is the base 5 representation of the number 465^8 a) 1231(5) b) 1141(5) c) 2214(5) d) 2351(5)

Answer  

Option C : 2214(5)

Solution

The given number is 465 in base 8. To convert this number to base 5,we need to convert this number to base 10, then only we can compute the number in base 5

Step1 : Convert 465 to the base 8 to base 10

4 x 82=256

6 x 81=48

5 x 80=5

Adding 256 + 48+ 5 = 309(10)

Step2 : Convert 309(10) to base 5  

5 | 309  

5 | 61 |4

5 | 12 | 1

5 | 2  | 2

5 | 0  | 2

Therefore Answer = 2214(5 )

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
