Question

Work out the area of the parallelogram. 13 cm 790 21 cm

Answer 1

Answer:

The area of parallelogram can be found by product of its base and height. The calculations are shown below:  

Step-by-step explanation:

We know that,

Area of parallelogram = base × height

assume base to be 21 cm.

Then,

sin 79° = $\frac{height}{13}$

∴ height = 13 × 0.98 = 12.74

Area of parallelogram = 21 × 12.74

                                   = 267.54 $cm^{2}$

The area of parallelogram is calculated as 267.54 $cm^{2}$
