Answer 1

Answer:here ,,it's a right angled triangle Step-by-step explanation:SO AREA =1/2 ×BASE ×ALTITUDE 1/2 ×12×161×6×16 96 is the area of that triangle hope it helps

Answer 2

Answer:

Area=96 sq units

Step-by-step explanation:

Three sides

a=20m

b=12m

c=16m

S=(a+b+c)/2

S=(20+12+16)/2

S=48/2

S=24

Area=$\sqrt{s(s-a)X(s-b)X(s-c)}$

Area=$\sqrt{24(24-20)X(24-12)X(24-16)}$

Area=$\sqrt{24(4)X12X8}$

Area=$\sqrt{9216}$

Area=96 sq units
