What is the perimeter of the shape below, given a = 9.60, b = 9.33, c = 4.46, d = 8.56, e = 8.61
GalinKa [24]

Answer:

The perimeter of the shape is of 40.56 units.

Step-by-step explanation:

Perimeter of a shape:

The perimeter of a shape is the sum of the lengths of all its sides.

In this question:

The sides are a = 9.60, b = 9.33, c = 4.46, d = 8.56, e = 8.61.

So

P = a + b + c + d + e = 9.6 + 9.33 + 4.46 + 8.56 + 8.61 = 40.56

The perimeter of the shape is of 40.56 units.
