Question

in a triangular field having sides 30 m, 72 m and 78 m, the length of the altitude to the side measuring
72 m is
plz answer with full explanation ​

Answer 1

Answer:

a triangular field having sides 30m 72m 78 m

s = (30 + 72 + 78)/2 = 90

Area of Triangular Field = √90 (90-30)(90-72)(90-78)

= √90 * 60 * 18 * 12

= √30 * 3 * 30 * 2 * 6 * 3 * 6 * 2

= √ ( 30 * 3 * 2 * 6)²

= 1080 m²

Area of Triangle = (1/2) * 72 *  (length of the altitude to the side measuring 72m)

=>   (length of the altitude to the side measuring 72m) = 1080 * 2/72

= 1080/36

= 30 m

length of the altitude to the side measuring 72m = 30 m
