Answer 1

Answer:

Where is the figure in this question.

Answer 2

Answer:

The perimeter of a simple closed figure is the sum of the measures of line-segments which have surrounded the figure.

Perimeter of a Figure

Perimeter of ∆ABC = length (AB + BC + CA)

Perimeter of the quadrilateral DEKN = length (DE + EK + KN + ND)

Perimeter of the hexagon PQRSTU = length (PQ + QR + RS + ST + TU + UP)

The perimeter of a circle is the measure of its circumference. The perimeter of the circle of center O is its circumference.

Perimeter of the playground

Perimeter of the playground = 112 m + 85 m + 69 m + 102 m

Perimeter of the playground = 112 m + 85 m + 69 m + 102 m = 368m

Perimeter of the playground = 112 m + 85 m + 69 m + 102 m = 368mKen walks 368 m around the playground, i.e. around the perimeter, every morning.
