In the given figure ABCD is square and OE = 7 cm.
The perimeter of the figure is :
Answer & explanation
Correct answer: option 3
The answer is Option 3: 64 cm
OE = 7 cm = radius of semicircle
Here, OE = OA = OD = 7 = radius and
AD = OA + OD = 7 + 7 = 14 cm = AB = BC = CD = side of the square
Perimeter of Semi-Circle =$πr=\frac{22}{7}×7=22$cm.
So, Perimeter of the above figure = Perimeter of Semi-Circle + AB + BC + CD = 22 + 14 + 14 + 14 = 64 cm.
