Question

can anyone solve this???​

Answer 1

Let the ratio be x

base = 3x  height = 2x

area of triangle = 108

⇒21×2x×3x=108⇒3x2=108⇒x2=36x=6Base=3x=3×6=18cmheight=2x=2×6=12cm.

=b+2/h+8

=18+2/12+8

=20/20

=1

this is the answer..

If u think my answer is correct mark me as brainlist

Thank you

Answer 2

Answer:

1

Step-by-step explanation:

We know that, area formula of a triangle is

(½×base×height).

Here, base is considered as b and height is considered as h.

Their ratio is 3:2.

So, let the common ratio be x. Then,

b=3x

h=2x

According to condition,

½×3x×2x=108

or, x² = 108×2/3×2

or, x² = 36

or, x = √36

or, x = 6

Therefore, b= (3×6) m = 18m

and, h= (2×6) m = 12 m

So, b+2/h+8

= 18+2/12+8

= 20/20 = 1
