Maths

Today during maths my maths group and I did a maths problem. The maths problem we did was down below
I did place value partitioning to solve my answer.

Marilyn needs to fertilise her front lawn. It measures 20 metres by 35 metres. Each bag of the fertiliser that she plans to use covers approximately 200m2. How many bags should she buy?



Remember: length X width
1.
20 x 30 = 600
20 x 5 = 100
600 + 100 = 700
20 x 35 = 700
2.
700 ÷  2 = 350
700 ÷ 200 = 3.5
3.

She should buy 4 bags and use half of it and use the other half when she does her lawn again
