The blanket is 2.25 metres long and 1.8 metres wide. what is the area of the blanket? write the answer in centimetres.

Answer 1

$13608

Step-by-step explanation:

Amount saved by Bao per month = $179

Amount saved by Bao per month = Ada's savings - 179

Amount saved by Ada = $179 + $145

Amount saved by Ada per month = $324

time = three and a half years

We convert years to months:

12 months = 1 year

time = 3(12) + 1/2(12) = 36 + 6

time = 42 months

Amount Ada saved = $324 × number of months

Amount Ada saved = $324 × 42

Amount Ada saved = $13608
