Question

The sides of triangle ABC are in the ratio 2:3:2. The perimeter of the triangle is 147 cm. What is the length of its longest side?

Answer 1

Answer:

Step-by-step explanation:

2 + 3 + 2 = 7

Side AB = 2/7

Side BC = 3/7

Side CA = 2/7

Side BC is the longest

3/7 of 147 =

147 / 7 * 3

147/ 7 = 21

21 * 3 = 63cm

Answer is 63cm

Answer 2

Answer:

let sides were 2x ,3x and 2x

perimeter=147

7x=147

x=21

so sides

42,63,42cm

longest side 63cm
