Diagonal

Diagonal of the rectangle has length 46.4 cm. Angle between diagonal and londer sife of rectangle is 22°.

Calculate area of the rectangle.

Result

S =  747.79 cm2

Solution:

$a = 46.4 \cdot \sin 22 ^\circ = 17.38 \ cm \ \\ b = 46.4 \cdot \cos 22 ^\circ = 43.02 \ cm \ \\ \ \\ S = ab = 747.79 \ \text{cm}^2$
