Question

There is a triangular park with sides 7 m, 8m and 5 m. Taking Park as ABC, AD is
perpendicular on BC. If trees are planted at A, B, C and D. Find the distance between
trees at A and D​

Answer 1

Answer:

Now , perpendicular line dropped from A would actually be the median of the given triangle ABC and would bisect BC

Step-by-step explanation:

Now length of BC=5cm

so half of BC =5/2=2.5cm

Now, BD=2.5cm and AB=7cm so, use pythagoras theorem over here,

Therefore, (AB)²=(AD)²+(BD)²

Now, 49-6.25=AD²

so, 42.75=AD², so

AD= 3/2×19^1/2
