Answer 2

Answer:

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

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

Step-by-step 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.

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

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

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.
