Best Answer

Square of the hypotenuse is equal to the sum of the squares of the other 2 sides. Therefore 28*28 + 28*28 =784+784 =1568. Square root 1568 = 39.598ft or 39ft 6and 17-20ths inches. Or just over 39ft 6and threequarters inches.

If the area of a square is 72 sq in find the radius?

The radius of a square is the radius of the circumcircle, ie the distance from the centre of the square to any vertex, which is half the length of the diagonal of the square. Using Pythagoras: diagonal^2 = side^2 + side^2 → diagonal = √(2 x side^2) area = side^2 → diagonal = √(2 x area) radius = 1/2 x diagonal = 1/2 x √(2 x area) → radius = 1/2 x √(2 x 72 sq in) = 1/2 x √(144 sq in) = 1/2 x 12 in = 6 in.
