Ana Lopena's Pythagoras Scribe Post

12. While shopping online, Jin Hun finds a square rug with an area of 11m2. He needs to know if it will fit in his 4m x 5m bedroom.

a) Estimate the side length of the rug to one decimal place.

b) Check your estimate with a calculator.

c) Will the rug fit? Explain.

Yes, because the side length of the room is 4m and 5m and the side length of the rug is 3.3m.

13. Stella is planning an outdoor wedding. She would like a square dance floor with an area of 115m2.

a) Determine the side length of the nearest tenth of a metre.

b) Stella finds out that the dance floor will be made up of 1m2. What are the two side lengths the dance floor can have that are the closest to what she wants?

10m x 10m or 11m x 11m

c)What are the two square areas for the dance floor that Stella can choose from?

100m2 or 121m2

d) Which area will Stella choose? Explain.

I think that Stella will choose 121m2 because it is closer to the area that she wanted.
