Answer:
Step-by-step explanation:
P = 240
S = 240/2 = 120
By Heron's Formula
area \: = \sqrt{s(s - a)(s - b)(s - c)}area=
s(s−a)(s−b)(s−c)
area = \sqrt{120 \times 8 \times 70 \times 42}area=
120×8×70×42
area \: = 1680area=1680
Area of the triangle = 1/2 *B*H
= 2 × 1680 = 50 × H
= 3360 = 50 × H
H = 3360/50
Height = 67.2 dm
The answer is 67.2 dm
