The ratio of altitude and base of a triangle is 1 ratio 2 and area is 9 square metre find its base and altitude

It's base is 6m and altitude is 3m.

Step by Step Explanation.

Let the altitude(h) and base(b) of the triangle be x m and 2x m respectively.

Area(A)= 9 m^2

We know,

A=1/2*b*h

or, 9= 1/2*2x*x

or, 9*2= 2x^2

or, 18= 2x^2

or, 18/2 = x^2

or, 9 = x^2

or, 3^2= x^2

so, x = 3 m

Hence, altitude =x= 3m

and, base = 2x=2*3= 6 m

what level of math? also i don't need to be paid if i can you.

what is the model?
