Yuri [45]
<h2>Dimensions of enlargement is height is 16 inch and width is 12 inch.</h2>

Step-by-step explanation:

A picture has a height that is 4 / 3 its width.

Let h be the height and w be the width.

Given that

                h=\frac{4}{3}w

Area of picture is given by 192 inch²

            A = 192 inch²

          h x w = 192

     \frac{4}{3}w\times w=192\\\\\frac{4}{3}w^2=192\\\\w^2=144\\\\w=12inch\\\\h=\frac{4}{3}\times 12\\\\h=16inch

Dimensions of enlargement is height is 16 inch and width is 12 inch.
