Question

The sides of a triangle are in the ratio 2: 3 : 4 and its perimeter is 63 cm. What are the lengths of its sides?​

Answer 1

Answer:

Let, the sides be 2x , 3x and 4x

Perimeter of a triangle ∆ = sum of all sides

63 = (2x+3x+4x)

63 = 9x

x = 63 / 9

• x = 7

Substituting x , we get

2×7 = 14

3×7 = 21

4×7 = 28

Thus, the sides are 14cm , 21cm and 28cm.

Answer 2

Answer:

21 cm and 28 cm

Step-by-step explanation:

The sides of the triangle are in the ratio 2: 3: 4 which mean 2 + 3 + 4 = 9.

The perimeter of the triangle = 63 cm.  

The solution is 2/9 x 63 = 14; 3/9 x 63 = 21; 4/9 x 63 = 28.

The lengths of the sides are 14 cm,

21 cm and 28 cm respectively.
