Answer 2

Step-by-step explanation:

let length of altitude be x,

And base of triangle be y;

given that y=3/4x

Area of triangle=1/2×base×altitude

=1/2×y×x

=1/2×3/4x×x

=3/8x^2

now;

base=y+2=3/4x+2=3x+8/4

altitude=x+3

area=1/2×base×altitude

=1/2×(3x+8)/4×(x+3) =3/8x^2

=(3x+8)(x+3)/8=3/8x^2

=3x^2+9x+8x+24=3x^2
