Answer:

150

Step-by-step explanation:

Triangle ADB is a right angle triangle

Use Pythagorean theorem to find out the length of AD

c^2=a^+b^2

a=16, hypotenuse(c)=20

Plug in the values and find out b

20^2=16^+b^2

400= 256 +b^2

Subtract 256 from both sides

144=b^2

Take square root on both sides

b=12

The length of AD is 12

Now we find length of CD using pythagorean theorem

c^2=a^+b^2

b=12, hypotenuse(c)=15

Plug in the values and find out b

15^2=a^2+12^2

225= 144+a^2

Subtract 144 from both sides

81=a^2

Take square root on both sides

b=9

Length of CD = 9

Length of CB = 9+16=25

Area of the triangle ABC= \frac{CB*AD}{2}

=\frac{25*12}{2}=150
