The area of the given parallelogram is approximately
[tex]268cm^2[/tex]
Data given;
The area of a parallelogram is the product of its two sides and the sine of the angle (if given).
So the formula of our parallelogram is
[tex]A = a.bsinx[/tex]
x = angle
Substitute the values and solve.
[tex]A = 13 * 21 * sin79\\A = 267.98cm^2\\A = 268cm^2[/tex]
From the calculation above, the area of the parallelogram is approximately [tex]268cm^2[/tex]
