  • On a calculator

  • half of 4.5 is 2.25 so 4.5+4.5+4.5+4.5+2.25 = 20.5

    or use the squared button on a calculator which usually looks like an x with a little 2 above it. you just press 4.5 then the squared button then =

  • Yes, it’s 4.5 squared, i.e. 4.5 x 4.5.

    Work in two stages thus:

    4 x 4.5 = 18

    0.5 x 4.5 = 2.25

    Then add your two answers

    18 + 2.25 = 20.25
