Answer 2

Answer:

Finding area of ΔABC

Using BC as base and

AD as height

Here,

Base=BC

=9cm

Height=AD

=6cm

Area of ΔABC=1/2 x Base x Height

=1/2 x BC x AD

=9 x 3

=27cm

Now we have to find EC which is height corresponding to base AB

So, finding area using EC as height and AB as base

Base = AB = 7.5 cm

Height = EC

Area of ΔABC = 1/2 x Base x Height

27 =1/2 x 7.5 x EC

27 x 2

----------. =EC

7.5

27 x 2 x 10

------------------. = EC

75

9 x 2 x 10

-------------------. = EC

25

9 x 2 x 2

--------------------. = EC

5

36/5 = EC

7.2=EC

EC = 7.2cm

therefore, Area of ΔABC is 27cmsquare

And, height CE is 7.2
