What is Diagonal of Square?
The line stretching from one corner of the square or rectangle to the opposite corner through the center of the figure is known as the diagonal. Any square that has two diagonals are equal in length to each other.
Here, the length of the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.
The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs.
From Pythagorean theorem, diagonal of square A is:
diagonal² = 30² + 30² = 1800
diagonal = [tex]\sqrt{1800}[/tex] = 42.43 ft
which is longer than the banner.
Thus, the school banner can fit across the length of the concession stand is 42.43 ft.
