Question

In the adjoining figure, AC = 15 cm, AB = 12 cm and BD = 8 cm. Find:
(a) the area of the triangle.
(b) the length of CE.

​

Answer 1

Answer:

Step-by-step explanation:

BD ⊥ AC

so BD is altitude

so area of ΔABC

=1/2* AC*BD

=1/2*15*8

=120/2

=60 cm ²

(b) CE ⊥ AB

soCE is altitude

so area of

ΔABC=1/2*AB*CE

60=1/2*12*CE

60=6CE

CE=60/6=10 cm
