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 :)
Answer:
I think The White one is 3.61 and the purple is 10....
Step-by-step explanation:
we just divide the shapes into separate and find the area of each separate shape
all of those r correct :)
Answer: 35,40,45,50,55
That is the answer to the 1st part.
Step-by-step explanation:
When competing the square, you want to have
at the end, and using the fact that the x term and coefficient are really
, we see that the third option is the most efficient way to start
