Okay so where's the math question(s)?
Answer:
144
<h3>
Step-by-step explanation:</h3>
If 48 is the perimeter, then 48 divided by 4 is one of the side lengths.
L x W = Area
12 x 12 = Area
12 x 12 = 144
Area = 144
X=4 & y=3
Explanation:
Picture
Let the temperature at 10am be x, then
x + 8 = 56
x = 56 - 8 = 48 degrees F
Let y be the temperature at 8am, then
y - 2 = 48
y = 48 + 2 = 50 degrees.
