5(4) - (- 2) = 18
20 + 2 = 18
22 ≠ 18

It is not a solution.

Math 170

Alinara [238K]

The given sides are 12 cm, 15 cm and 21 cm

Shortest side is 12 cm

As given that in real the shortest side is 200 m

So 12 cm=200 m

then 1 cm = $\frac{200}{12}=\frac{50}{3}$

Hence 15 cm = $\frac{50}{3} * 15 = 250$ m

21 cm = $\frac{50}{3} * 21 = 350$ m

So,,

15 cm in the photograph is 250 m long .

21 cm in the photograph is 350 long.
