Question 8 (a) There were 9 intervals separating 10 seeds. Each interval was 25cm. 9 × 25cm = 225cm or 2.25m (b) Since there were 600 cm/ 25 cm = 24 intervals, they could separate 25 seeds.

Question 9 81 sq cm - 36 sq cm = 45 sq cm Also 81 = 9×9 and 36 = 6×6, and 9-6=3 Perimeter of square B = 4 × 9 = 36 cm

Simple and easy to understand. 👍👍

For qn 8b) shouldnt the answer be 33 seeds ? 800cm / 25cm = 32 intervals. No of seeds 32 + 1 = 33. Pls advise. Thks

Hello Pauline. If the distance is 8m then yes, there would have been 32 intervals. I had read the distance as 6m.

Have you attempted this question before and can verify the distance stated in the question is 8m, Pauline?

I've not done this qn before but I thought the qn says 8m from start to end point...

Xavier just need a pair of reading glasses... like i do... haha.

Haha... I think so too 😁 !

I stand corrected! Mister Yeo has been very kind to send me a zoomed-in screen catch of the distance stated in the question. I need a donation for a pair of progressive lenses lol

Thank you Pauline for pointing out the mistake. Sorry, it was not intentional.

No worries.. My girl did and was comparing with your answer. I must say the image wasn't clear enough, it looks like 6m too..

Always good to have contributors cross check one another so that we keep the solutions accurate. Thank you once again to you and your princess.

Thanx
