Question

The diagram shows a parallelogram.

Answer 1

Answer:

55cm^2

Step-by-step explanation:

Answer 2

Answer:

27.44 square cm

Step-by-step explanation:

If the length of parallelogram is a and b and angle between side a and b is $\alpha$.

Then area of parallelogram = $a*b*sin(\alpha ) = ab sin(\alpha )$

Given side length 4 cm and 7 cm

angle between them = 100°

value of sin(100°) = 0.98

Thus, area of given parallelogram = 4*7*sin(100°) = 28*0.98 = 27.44

Thus, area of given parallelogram is 27.44 square cm.
