Answer:side one is 8cm

Side 2 is 8cm

Side 3 is 15 cm

Step-by-step explanation:

The perimeter of a shape is the distance around the shape. The perimeter of a triangle is the sum of the sides of the triangle.

Let x represent the length of side one and side 2. Since they have equal length, the sum of their length is x + x = 2x cm

Side three is one cm shorter then twice the length of side one. This means that the length of side three would be 2x - 1

The perimeter of a triangle is 31cm. Therefore,

2x + 2x - 1 = 31

4x - 1 = 31

4x = 31 + 1 = 32

x = 32/4 = 8 cm

Side three = 2×8 - 1 = 16 - 1 = 15

Papessa [141]
Minimum: 37
maximum: 208

mean: (37 + 43 + 54 + 83 + 102 + 117 + 160 + 208)/8 = 100.5
median: middle number (83 + 102)/2 = 92.5
