The area of a square bedroom is 144 square feet. what is the length of one wall?
Rufina [12.5K]
The answer is:  "12 feet" .
________________________________
Note:  In a square, the length of EACH of the four sides of the square is the same.

Area = Length * width. 

For a square, length = width.

So for a square, Area = length * width = (length of a side)² = s² ,

Given:  A = s² = 144 ft² ;

Solve for the positive value of "s" .
________________________________
  →  s² = 144 ft² ;  Take the "square root" of each side ;

  → √(s²) = √(144 ft²) ;

  →   s = 12 ft.
_______________________________
The answer is:  12 ft.

when hpotonouse is c and hthe lgs are a and b
a²+b²=c²

given
leg is 8
hypotonuse is 13

8²+b²=13²
64+b²=169
minus 64 from both sides
b²=105
sqrt both sides
b=√105

find total perimiter
8+13+√105=21+√105

times 1/32 for scale
