To triple this number, you can triple the whole number, triple the fraction, then add them together.

3*3=9
1/2*3=3/2 (or 1 1/2)

Add them together.

9+1 1/2= 10 1/2

Max measures the diagonal of a square room to be 32feet find the perimeter and area of the room round answers to the nearest ten

Hello!

To find the side length of a square with the diagonal you use the equation

$a = \sqrt{2} \frac{d}{2}$

a is side length
d is diagonal length

Put in the values you know

$a = \sqrt{2} * \frac{32}{2}$

Divide

$a = \sqrt{2} * 16$

Multiply

a = 22.6

All the sides are 22.6 feet

Add all the sides

22.6 + 22.6 + 22.6 + 22.6 = 90.4

The answer is 90.4

Hope this helps!
