Question

perimeter of a triangle is 12.5 cm and the ratio of its length of its side is 4 : 2 :3 construct the triangle ​

Answer 1

Answer:

4X + 2X + 3X = 12.5

9X = 12.5

X = 12.5/7

1.38

side of ∆ are 5.6cm , 2.8cm , 4.1cm

Answer 2

Let the sides be 4x,2x,3x. (4:2:3)

Perimeter = 12.5 cm

4x+2x+3x = 12.5

9x = 12.5

x = 12.5÷9

x = 1.39 (approx)

first side = 4x = 4×1.39 = 5.56 cm

second side = 2x = 2×1.39 = 2.78 cm

third side = 3x = 3×1.39 = 4.17 cm

Now you can construct it.
