Here, I think I can help you out:
1. 21 ÷ 3
= 7
Therefore, the length is 7cm².
2. 35 ÷ 7
= 5cm²
- And so on. Simply divide the area by the length of the side given; you can answer up to question six using this strategy.
7. All sides of a square are the same length.
7 x 7
= 49cm²
9. 2 x 3.5
= 7m²
- The formula to find the area of a square/rectangle is length x width. Just multiply the given lengths for the answers :)
Use the formula T(x) = 0.01x2^x
X is the number of days.
T(8) = 0.01 x 2^8
T(8) = 0.01 x 256
T(8) = $2.56
Answer:
8 (see work)
