Perimeter is 3 times and little more larger than diameter.
So,
14 multiplied to 3 is...42.
42 is the answer!

as the diameter is 14
so, the radius will be 7 we assume it a complete circle then we find cirumference of full circle i.e 2πr
so the circumference of the complete circle is 2×22/7×7 = 44
so the circumference of the semi cirlce or the protector is 44/2 = 22
