Question

What is the perimeter of the figure?​

Answer 1

40 cm

Explanation:

perimeter = Circumference + 2 × length of rectangle

perimeter = 2 × 9 + 2 × 22/7 × 7/2

Perimeter = 18 + 22 = 40 cm

Answer 2

Oh! We should start with finding the lngths of the "curvy sides". As you can see there are 2 semi circles which we can combine to make one circle with a diameter of 7. The formula for the circumference of the circle is 2πr which is also equal to the diameter x π. SO the circumeference is 7π which is this case equals 22 since they are telling us to use π as 22/7. I'm not sure about the rest but I hope this helped a little!!
