Rectangle area calculation method
Diagonal d: Angle α°:

Rectangle

A rectangle is a geometric shape that has four right angles (90°) and opposite sides are equal and parallel.
Rectangle area formula Rectangle area formula Along the diagonals and the angle between them where d is diagonal, α° is the angle between them in degrees.

Solution:
S =
d2·sin(α°)
2
=
992·sin(76°)
2
=
9801·0.97
2
=
9506.97
2
=
4753.485

a: Area of a rectangle with a diagonal 99 and the angle between them 76° equal to 4753.485
