Answer 1

Answer:

It's 15 cm

Step-by-step explanation:

Area of small square = a^2

a^2 = 13^2

= 169 sq.cm

Let side of unknown square be x.

Area of shaded region = Large square area - Small square area

56 = x^2 - 169

x^2 = 225

x = 15 cm

Answer 2

Answer:

15 cm

Step-by-step explanation:

Let the length of side's of bigger square be X.

Now,

(Area of larger square) - (Area of small square) = Area of shaded region

Hence,

-> X^2 - (13)^2 = 56

-> X^2 - 169 = 56

-> X = 15 cm
