Answer:51 cm^2
Explanation:
You can consider this as a circle.
To find the area of a given sector of a circle you have to use this formula
Angle/360 x π x r ^ 2
in this case you can find the angle of one side by substracting 180 from 120
180-120=60
then
60/260 x π x 7^2 = 25.6563 rounded of to 26 , multiply this by 2 to get the total area .
total area = 51 cm^2
