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
Rasek [7]
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!
