Answer 1

Answer:

area=12 square unit

Step-by-step explanation:

let base is b cm and altitude is 2/3b cm

then a/q question,

1/2×b×2/3b= 1/2×(b-2)×(2/3b+2)....b comes out 6 ...putting the value of b in formula of area of triangle we get area =12

Answer 2

Answer:

12

Step-by-step explanation:

let base =b altitude=2/3
