Question

construct a angle pqr whose perimeter is 12 cm and the length of whose side are in the ratio 2:3:4

Answer 1

Answer:

Step-by-step explanation:

Let x be the common multiple

Therefore the sides are 2x,3xand 4x

Sum of all side is => 2x + 3x+4x= 9x

But

Sum of all side=Perimeter

Therefore

9x =12

X =1.3

First side =2*1.3=2.6

Second side =3*1.3=3.9

Third side =4*1.3=5.2

Now you can construct the triangle with the given sides
