Question

I need to find the exact perimeter of the square.

Answer 1

P = 79.2

Step-by-step explanation

We want to find the perimeter of the square given only its diagonal.

To do that, we use the formula:

`P\text{ = 2 }\sqrt[]{2}\cdot\text{ D}`

where D = length of diagonal

The diagonal of the square is 28.

Therefore, we have that:

`\begin{gathered} P\text{ = 2 }\sqrt[]{2}\cdot\text{ 28} \\ P\text{ = }2.828\cdot\text{ 28} \\ P\text{ = }\cong79.2 \end{gathered}`

That is the answer.
