Answer 2

Answer:

15 cm is the new dimensions of new photograph

Step-by-step explanation:

initial dimension of shorter side = 8 cm

initial dimension of longer side = 10 cm

final dimension ofshorter side = 12 cm

finial dimension of longer side = x cm

The enlargement always ensure the aspect ratio

aspect ratio = lonter side/shorter side

equating, $\frac{10}{8}$ = $\frac{x}{12}$

Solving for x,

10 × 12 = 8 × x

$x = \frac{10 x 12 }{8} = \frac{120}{8 } = 15$

        /\

        that says 10 x 12

longer side is 15cm
