Feet
Step-by-step explanation:
I don't get your question, can u type it again more clearly? thanks
we know that
the area of the complete square is equal to

where
b is the length side of the square

so

m²
the area of one corner is equal to the area of a triangle

so
the area of
corners is equal to

the area A of the resulting figure as a function of x is equal to
area of the square minus the area of
corners
m²
the answer is
m²
<span>You would need a ladder length of 28 feet. If you compute the hypotenuse of a right triangle, or 26 feet squared plus 9 feet squared, you get an answer of 757, the square root of which is 27.51 feet, to give yourself enough ladder, we round that number up to 28 feet.</span>
