A square has an area of 144 in^2. What is the length, to the nearest inch, of the diagonal?
zysi [14]

The length of the diagonal is 17 in

Explanation:

The area of the square = 144 \ in^2

The formula for area of the square is given by

 A=a^{2}

144=a^{2}

 12=a

The sides of the square are 12 inches.

The length of the diagonal of a square can be determined using the Pythagorean theorem.

Let d be the diagonal of the square.

Thus, we have,

$12^{2}+12^{2}=d^{2}$

144+144=d^{2}$

      \sqrt{288} =d

      16.97=d

Rounding off to the nearest inch, we get,

d=17 \ in

Thus, the length of the diagonal is 17 in

A. Write an expression for the area of the rectangle<br><br> B. Find the area for x=2
Klio2033 [76]
Hello! 
Your questions are quite simple:

A.
Area for rectangle [formula]: A=wl
So your answer is 3×(2x+5)

Explanation:
Since you only have a minimum amount of a number and variable all you have to do is multiply them both in order to get the area, however here we are only asked for an expression so basically, we are leaving out the answer and writing down the multiplication. 

B.
3×(2×2+5) = 27

Explanation:
I think the first explanation is very similar to this one, so I think you'll understand it.

Hope this helped!
