Question

In a right triangle ABC,Right angled at B ,AB=9 cm,AC=15 cm and D,E are the midpoints of AB and AC respectively, then the area of triangle ADE is​

Answer 1

Answer:

Step-by-step explanation:

By Pythagoras theorem

AC²=AB²+BC²

15²=9²+BC²

225-81=BC²

144=BC²

√144=BC

12=BC

BC=12cm

Area of triangle =base*hieght/2

Area =12*9/2

Area =6*9

Area =54cm²
