Step-by-step explanation:

Answer 2

$\huge\sf{\underline{\underline{Answer}}}$

The longest side is 50 cm.

▪Given :

• Ratio of the sides = 1 : 3 : 5
• Perimeter = 90 cm

▪To find :

• Length of the longest side

•Let the sides be -

1. One as x
2. Second as 3x
3. Third as 5x

[ Perimeter = Sum of all sides]

⇒ 90 = x + 3x + 5x

⇒ 90 = 9x

⇒ x = 90/9

⇒ x = 10

• Value of 3x

⇒ 3(10)

⇒ 30

Measure = 30 cm

• Value of 5x

⇒ 5(10)

⇒ 50

Measure = 50 cm

Longest side = 50 cm

∴ The longest side is 50 cm.
