Question

base of a triangle is3 times its height if the area of the triangle is 300 cm ² find the length of its base and altitude

Answer 1

Answer:

Step-by-step explanation:

let height = x cm

then base = 3x cm

area = 300 cm sq.

1/2 × b × h = 300

1/2 × 3x × x = 300

3x^2 / 2 = 300

3x^2 = 300 × 2

3x^2 = 600

x^2 = 600 / 3

x^2 = 200

x = √200 cm

height = x = √200 cm

base = 3x = 3√200 cm

be brainly

Answer 2

areaof triangle =1/2*base*height
base is 3 times =3x.
then. height is x

300=1/2*3x*x
300*2=3x^2
600 =3x^2
600/3=x^2
200=x^2
x=√200

height =√200
so base is 3x=3√200

hope it's it's help you

thanks.....
