Perimeter Triangle:Square 2:::::3 Sq->Area->81cm² Sides->9cm Perimeter-> 9x4=36cm 3u->36cm u-> 12cm 2u->24cm(perimeter of ∆) Side of ∆-> 24÷3=8cm(ans)

Thanks:)

2u=4.56-1.28....once u found u..u can solve lo

U= 1.64l

Jug = 4.56 + 1.64 = 6.2l

U r almost there..compare the models..can u see 2 units can be found?

So the model is correctly drawn?

Yes it is. U see 4.56 being equal to 2 units and 1.28? From here u can work out what is 2 units..

Thanks!

You may draw in this way too.

Thanks!

Well done, Michelle Yap :)

Haha... Thanks. Learn thru u too. 😉 I can learn and apply.

Michelle Yap I am not allowed to post using Concept Math logo (only personal postings). But usually CM has a few of us doing solutions and postings and usually we will post on CM FB and then share ... So will continue to post in PSLE 2016 :) and if I were the one who do the solutions then I will continue to share here as well. :)

Great... it benefits me a lot. I am preparing myself to revise with the younger ones for the coming SA2 and helping my niece too. I definitely look thru all the posting in CM FB.

ic ic thanks

thanks！

Yes

Okay thanks :)

5 thousandths is written as 5/1000 as a fraction. To change a fraction to a decimal divide the numerator (5) by the denominator (1000).

Yep Tenths, one zero, one decimal place Hundredths, two zeros, two decimal place Thousandths, three zeros, three decimal place
