Answer:
Option C. 144 square inches is the correct answer.
Step-by-step explanation:
We have been given a square with one side with a measurement of 1 foot and we have to calculate the area in square inches.
First we know that 1 foot of length = 12 inches on scale
Therefore side of the square is 12 inches
Now the area of the square will be = (Side×Side) = (Side)²
= (12)² = 144 square inches.
So the area of the square will be 144 square inches.
