let the common ratio be x
therefore first side=13x ,second side =14x, third side =15x
since perimeter = sum of all three sides
42cm= 13x+14x+15x
42cm=42x
x=1cm
first side=13cm, second = 14cm, third =15cm
find height by drawing a perpendicular and then find area with formula a=1/2*base *height
therefore first side=13x ,second side =14x, third side =15x
since perimeter = sum of all three sides
42cm= 13x+14x+15x
42cm=42x
x=1cm
first side=13cm, second = 14cm, third =15cm
