Question

triangle ABC is right angled at A. AD is drawn perpendicular to BC. if a b is equal to 5 cm and ac equal to 12 cm, find the area of triangle ABC.also find the length of AD

Answer 1

Answer:for the area of triangle

Area=1/2*b*h

=1/2*5*12

=30sq.cm

Further for length of ad

dab ~acb(AA TEST)

da/ac=ab/bc(CPST)

FOR BC

bc =13 cm(PYTHAGORAS THEOREM)

ad/12=5/13

ad=5*12/13

=60/13

ad=4.61cm
