Question

21. एक त्रिभुज की भुजाएँ 1 : 1.5 : 2. के अनुपात में हैं। यदि इसका परिमाप 13.5 सेमी है, तो प्रत्येक भुजा की लम्बाई ज्ञात कीजिए।

Answer 1

Answer:

3cm, 4.5cm, 6cm

Step-by-step explanation:

ratio of sides of length of triangle 1 : 1.5 : 2

perimeter of triangle = 13.5 cm

the sides of triangle will be 1x, 1.5x and 2x

sum of all sides of triangle is its perimeter

$1x + 1.5x + 2x = 13.5 \\ 4.5x = 13.5 \\ x = \frac{13.5}{4.5} \\ x = 3$

first side = x = 3 cm

second side = 1.5 x = 1.5(3) = 4.5 cm

third side = 2x = 2 (3) = 6 cm

hope you get your answer
