Answer:
10m
Step-by-step explanation:
<u>Perimeter</u> means adding up all of the sides of a shape.
One property of a square is that <u>all lengths of a square are the same</u>.
We also know squares have <u>4 sides</u>.
<u />
Lets set up an expression to solve the length for each side with variable S representing the length of a side:
4 * S = 40
Divide each side by 4:
S = 10
Therefore, each side of the square has a length 10m
<u />
(11*5)+(4*10)=95
11+4=15
Both are equal to the constraints of the word problem and there for justified.
The way you put it is confusing. I'll answer but the way you put it was confusing to me.
I am not sure, but the best answer should be 8 miles per hour
