Cyerra's Scribe Post

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

a) 10.7 (10)

b) 10 m or 11 m

c) 100 m or 121 m

d) She will choose 121 because it's closer to 115 m ²


a) 3

b) 1.5

c) 1.73

d) 0.23

10. Kai uses an entire can of paint on a square backdrop for the school play. The label on the can states that one can cover 27 m² of wall surface. Estimate the backdrop's side length, to one decimal place.

- 5.1 m

1. Answer in a short paragraph with diagrams.

- A and B equal to C. Whatever A is and whatever B is, you add it up and it always equals C.

2. Solve for the missing side length.

- 144 + 25 = 169

3. Is this a right triangle? Prove it.

- No, because A and B (8 and 6) don't equal the amount that C is (11).
