The perimeter of the given shape CDEF can be given by 46.5
How to find perimeter of a shape?
Perimeter of a shape can be calculated by adding the length of each side of the shape.
For instance,
perimeter of a rectangle = length + length + width + width
= 2 length + 2 width
= 2(length + width)
Perimeter of CDEF = CD + DE + EF + FC
= 7.4 + 14 + 12.1 + 13
= 46.5
Therefore, the Perimeter of CDEF is 46.5
