Direction: In the given figure ABCD is a square and radius of semi circle is 7 cm.
On the basis of the above information answer the questions.
The perimeter of the figure is.
Answer & explanation
Correct answer: option 4
Here, ATQ
AD = Diameter = 2 × radius, where radius = 7 cm
AD = 14 cm. = side of square
Now,
Perimeter = Sum of 3 sides of the square + length of arc of semi circle
= (3 × side) + πr = $(3×14)+\frac{22}{7}×7$ = 42 + 22 = 64 cm
