Question

Draw a triangle with perimeter 12cm of sides 1:3:3

Answer 1

✴ Hola ✴

Sum of all sides = Perimeter of a triangle

1x+3x+3x=12
7x=12
x=12/7
x=1.71

1(1.71)=1.71
3(1.71)=5.13
3(1.71)=5.13

Answer 2

Answer:

let the sides be x, 3x and 3x        AB=x BC=3x AC= 3x

perimeter= x + 3x+3x

12= x+3x+3x

12=7x

x=12/7

x=1.71

the other sides will be 3(1.71) ie. 5.13

therefore,

AB=1.71

BC=5.13

AC= 5.13

then you can draw it
