Question

in a triangle ABC BC is equal to 8 cm ab is equal to 16 cm and height corresponding to BC is equal to 10 cm find the area of triangle and the highest corresponding to a b​

Answer 1

Answer:

Step-by-step explanation:

Your mid-segment line (DE) splits the altitude of ABC into 2 equal parts. Your DEF area is half of the area of the rectangle you get by drawing perpendiculars from D and F to BC. That rectangle has an area equal to half the altitude of ABC times half BC ( since DE is mid-segment and half of BC). So area of DEF is (H/2*BC/2)/2. That's H*BC/8, and you are given H*BC/4=16. There you go !
