Answer 2

Answer:

10 , 9

Step-by-step explanation:

let the sides of 2 squares be x and y

Their areas are x*x and y*y

Perimeters are 4x and 4y

Given

${x}^{2} - {y}^{2} = 19$

$4x + 4y = 76$

$= > x + y = 19 \quad\{1\}$

Now

${x}^{2} - {y}^{2} = 19$

$= > {x}^{2} + xy - xy - {y}^{2} = 19$

$= > x(x + y) - y(x + y) = 19$

$= > (x + y)(x - y) = 19$

$= > 19(x - y) = 19$

$= > x - y = 1 \quad \{2 \}$

$\{1\} + \{2\}$

$= > (x + y) + (x - y) = 19 + 1$

$= > 2x = 20$

$= > x = 10$

$= > y = 9$

Therefore there respective sides are 10 and 9.

Hope it helps
