The diagram shows a parallelogram. 4 cm
7 cm
100°
Work out the area of the parallelogram.
Give your answer to 2 significant figures.

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 .

Then area of parallelogram =

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.
