Answer:

\huge\mathcal{\fcolorbox{aqua}{azure}{\red{✿Yøur-Answer♡❖}}}

⟹ \large\bf{\underline{\red{VERIFIED✔}}}

We know that s=(a+b+c)/2

here, a=15,b=36, c=39.

Therefore: s= (15+36+39)/2

s=45

And Area

= \sqrt{s(s-a)(s-b)(s-c)}s(s−a)(s−b)(s−c)

Therefore: area

 = \sqrt{45(45-15)(45-36)(45-39)}45(45−15)(45−36)(45−39)

According to the formula: area=(height × base)/2

Filling the information we have,

270 = (H * 39)/2

Therefore: H = 13.84
