Given:
Parallelogram with 2 given sides, 4cm and 7cm respectively, and angle between them = 100°
Required:
Area of the parallelogram to 2 significant figure.
Solution:
Area of the parallelogram = a*b*sin(θ)
a = 4cm
b = 7 cm
θ = 100°
Area of parallelogram = 4*7*sin(100)
Area = 28*0.9848
Area = 27.57
Area of parallelogram to 2 significant figure = 28 cm²
