Answer 1

(1)
`Perimeter = 20.2cm`

(2)
`Perimeter = 28.2cm`

Step-by-step explanation:

Given

(1): Triangle of Sides 7.8cm, 6.5cm, 5.9cm

(2): Equilateral Triangle of side: 9.4cm

Required

Determine the perimeter

Solving (1):

The perimeter is calculated by adding up the measure of each side.

So, we have:

`Perimeter = 7.8cm + 6.5cm + 5.9cm`

`Perimeter = 20.2cm`

Solving (2):

Using the same step in (1)

`Perimeter = 9.4cm + 9.4cm + 9.4cm`

`Perimeter = 28.2cm`
