Answer 1

ᴀɴswᴇʀ :-

• semiperimeter = 54 cm
• ratio of sides = 12:17:25

let their common ratio be x

we know,

• semiperimeter = sum of three sides / 2

• first side = 12x
• second side = 17x
• third side = 25x

• semiperimeter = 12x + 17x + 25x / 2

54 = 54x/2

x = 54×2 / 54

x = 2

• first side = 12x = 12(2) = 24 cm
• second side = 17x = 17(2) = 34 cm
• third side = 25x = 25(2) = 50 cm
