Question

ABC is right-angled at A. AD is perpendicular to BC, AB=5 cm, BC = 13 cm and
AC = 12 cm. Find the area of AABC. Also, find the length of AD.
12 cm
5 cm
13 cm​

Answer 1

Answer:

area of triangle ABC = 30cm square

AD = 4.6cm

Step-by-step explanation:

height = 5cm

breadth = 12cm

area = 1/2×d×h

=1/2×12×5

= 6×5

=30cm square

area of ABC = 1/2×b×h

30 =1/2×13×h

30 = 6.5 ×h

30/6.5=h

h. =4.6

AD=4.6 cm
