The area of the given parallelogram is 267.54 cm². The given triangle has two sides and an angle in between them.
What's the area of a parallelogram with two sides and an angle?
The area of the parallelogram is
Area = base × height sq. units
But if an angle between the two sides is given,
Area = side(1) × side(2) × sin (A) sq. units
Where A is the angle between side1 and side2.
Calculation:
Given that,
Side1 = 21 cm
Side2 = 13 cm
Angle A = 79°
So, its area = 21 × 13 × sin (79°)
= 273 ×0.98
= 267.54 cm²
∴ The area of the given parallelogram is 267.54 cm².
