Answer:

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

Explanation:

We know that,

Area of parallelogram = base × height

assume base to be 21 cm.

Then,

                 sin 79° =  [tex]\frac{height}{ 13}[/tex]

             ∴ height = 13 × 0.98 = 12.74

Area of parallelogram = 21 × 12.74

                                    = 267.54 [tex]cm^{2}[/tex]

The area of parallelogram is calculated as 267.54 [tex]cm^{2}[/tex].

What is a real-life example of a parallelogram?

  • The bug is moving in a moving bus, the bug is moving much faster relative to the ground to the bus.
  • Relative to the ground, the bug in a combination of velocities.
  • If the bus weren’t moving, the bug would cover the same distance on the bus as on the ground in a given interval of time

Hence,

Area of parallelogram = base × height

assume the base to be 21 cm.

Then,

                sin 79° =  [tex]\frac{hight}{13}[/tex]

            ∴ height = 13 × 0.98 = 12.74

Area of parallelogram = 21 × 12.74

                                      = 267.54[tex]cm^{2}[/tex]

The area of a parallelogram is calculated as 267.54[tex]cm^{2}[/tex]
