We know that
Applying the Pythagoras Theorem
c=²=a²+b²
where c is the diagonal of the wall
a=12 ft
b=6 ft
c²=12²+6²-----> c²=144+36-----< c²=180-----> c=√180------> c=6√5 ft
the answer is
<span>the exact length of the brace is 6</span>√5 ft
Add 26 to each side of the equation !
4*6 = 24. (4 dollars to spare)
(5*2) + (4*4) = 26 (2 dollars to spare)
