Answer 1

Answer:

Step-by-step explanation:

The formula for area of a triangle is,

A = (1/2) * b * h where b= base and h=height

Here Height = Half of Base.

So, let us assume base, b= x

therefore h= x/2

We are given that area, A = 144

Substitute in the above equation and find the value of x:

A = (1/2) * b * h

144 = (1/2) * x * x/2

Solve for x.

Answer 2

Answer:

height= 12cm   base=24cm

Step-by-step explanation:

they have given the height of the triangle is half of the base length

and area of the triangle =144cm²

let us consider base length of triangle is = a cm

then the height of the triangle is =a/2 cm

we know that

A=(1/2)b*h

144=(1/2)*a*(a/2)

144=a²/4

⇒a²=144*4

  a²=576

  a=24

we got the base length as a=24cm

so the height of the triangle is (a/2) =12cm

I think this answer is helpful to you.
