Question

find the area of the shaded region pls answer fast pls










​

Answer 1

Step-by-step explanation:

first find the third side of bigger triangle

12^2+5^2 = y^2

169=y^2

y = 13

so third side is 13

now find area of inner triangle

1/2×12×5

= 30

now find area of outer triangle using heron formula

find Semi perimeter which is 21

area = √21(21-15)×(21-13)×(21-14)

area = √21×6×8×7

area = √7056

area = 84

to find area of shaded region

=84-30

= 54
