A sidewalk tile measures $4$ feet by $5$ feet. How many square inches are in its area?

4 feet by 5 feet

4×5=20

Step-by-step explanation:

the area of the sidewalk tile measures 20 feet

Step-by-step explanation:

to find the are you first have to multiply the length and width so that would be 4 times 5 equals 20

Increase of 2°F/h Option 4.

Step-by-step explanation:

Here in the table time in hours is the independent variable (x) and temperature in °F is the dependent variable (y).

The initial temperature at x = 0 hour is 52°F and then the temperature increases by 2°F per one hour time spent.

Therefore, the temperature is increasing at a constant rate of 2°F per hour from an initial value of 52°F.

Hence, option 4 is correct.
