32 + 82 = diagonal2 (9 + 64) = 8.544
The diagonal is 7.21 feet.
A rectangle does not have a diameter, only circles or similar obects have diameters. A rectangle has a diagonal which is obtained by joining two opposite corners. Any two adjacent sides of the rectangle together with the diagonal form a right angled triangle and so the length of the diagonal can be derived using Pythagoras's theorem.
the diagonal in a paralleogram is not equal but the diagonals in the rectangle are congruent this is because the opposite sides of a parallelogram and rectangle are same parallel to each other but the adjacent sides of a parallelogram is not perpendicular where as the adjacent sides of rectangle is perpendicular to each other.
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
The length of the diagonal is about 16.03 feet.
The diagonal is 26cm
-- A rectangle has no 'formula'. -- The length of the diagonal is 24feet 10.62inches (rounded)
The diagonal length is about 18.44 inches.
This length (diagonal) = sq.rt ( l2 + b2 ) where 'l' is length of the rectangle and 'b' is the breadth of the rectangle.
The diagonal is 20.
You need to use trigonometry cosine (angle) = length/diagonal diagonal = length/cos(angle)
