Answer:

61.6

Step-by-step explanation:

Semiperimeter is equal to

a+b+c÷2= 70+108+122÷2

300÷2=150

the heron formula is equal to

√s(s-a)(s-b)(s-c)

√150(150-70)(150-180)(150-122)

√150*80*40*28

√14,112,000=

3,756.60

Now we got the area of triangle.

Since, the area of triangle is equal to 1/2* b*h

hence, 3756.6=1/2* 122 * h

3756.6 * 61* h

h= 3756.6/61 = 61.6.
