The area of a square = l^2
That means,
l^2 = 24 km^2
Take the square root of both sides
l =
l =
l =
l = 2
Now lets find the perimeter
Perimeter of a square, P = 4l
P = 4* 2
P = 8 inches
Answer:
+$90;
$1,600
Step-by-step explanation:
The equation, , given to us tells us much about the situation described above.
y = total pay
x = number of copies of Math is fun
1600 = y-intercept, that is the starting value or the pay he gets only if Sam sold 0 copy of Math is fun. That is, when x = 0, y = 1,600.
90 = unit rate or the change in the total pay for each copy of Math is fun that Sam sells.
Therefore, our answers would be:
+$90, and $1,600
