Answer:


\text{Perimeter of counter-top}=112\text{ inches}


\text{Area of counter-top}=784\text{ inches}^2

Explanation:

We have been given that a square counter-top has a side length of 28 inches. We are asked to find the perimeter and area of the counter-top.

We know that perimeter of a square is 4 times its side length.


\text{Perimeter of counter-top}=4* 28\text{ inches}


\text{Perimeter of counter-top}=112\text{ inches}

Therefore, the perimeter of the counter-top is 112 inches.

We know that area of square is square of side length of square.


\text{Area of counter-top}=(28\text{ inches})^2


\text{Area of counter-top}=784\text{ inches}^2

Therefore, the area of the counter-top is 784 square inches.
