Area of parallelogram #color(maroon)(A_p = 2.3# sq units

Area of parallelogram #A_p = a b sin theta#

where a & b are the two pairs of parallel opposite sides and #theta# the included angle between sides A & C

Given # a = 2, b = 3, theta = pi/8#

#:. A_p = 2 * 3 * sin (pi/8)#

Area of parallelogram #color(maroon)(A_p = 2.3# sq units
