height = x
base = 3x
14580/1080 = 13 .5
1/2 x b x h = 13.5
1/2 x 3x x x = 13.5
3x x x = 13.5 x 2
3x^2 = 27
x^2 = 27/3 = 9
x = √9
x = 3
height = 3 and base = 9
base = 3x
14580/1080 = 13 .5
1/2 x b x h = 13.5
1/2 x 3x x x = 13.5
3x x x = 13.5 x 2
3x^2 = 27
x^2 = 27/3 = 9
x = √9
x = 3
height = 3 and base = 9

Area of triangle => 14580 / 1080
=> 13.5
Let height =
and base = 3
area of traingle =
13.5 =
[tex]3x X x = 13.5 X 2 [/tex]
[tex]3 x^{2} = 27 x^{2} = \frac{27}{3} x^{2} = 9 x = \sqrt{9} x = 3[/tex]
so, height = x = 3
base = 3x = 3 x 3 = 9.
=> 13.5
Let height =
and base = 3
area of traingle =
13.5 =
[tex]3x X x = 13.5 X 2 [/tex]
[tex]3 x^{2} = 27 x^{2} = \frac{27}{3} x^{2} = 9 x = \sqrt{9} x = 3[/tex]
so, height = x = 3
base = 3x = 3 x 3 = 9.
