Question

The diagonal of a rectangle is 25 meters long makes an angle of 36 ° with one of the rectangle. Find the area and the perimeter of the parallelogram.

how to find the b to arrive to the area?
Please proof-read your work.

L = 25*Cos36 =
W = 25*sin36 =

Ar = L*W. = Area of rectangle.
Pr = 2L + 2W.

At = 0.5L*W = Area of triangle.
Pt = L+W+25.
