Answer 1

Answer:

(1) $Perimeter = 20.2cm$

(2) $Perimeter = 28.2cm$

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)

$Perimeter = 9.4cm + 9.4cm + 9.4cm$

$Perimeter = 28.2cm$
