Question

The sum of two square area is 117 m^2 . If its perimeter difference is 12m . Then find the side of both square



​

Answer 1

Answer:

Step-by-step explanation:

Let the side of sq 1 be x and that of 2 be y

1 condition

X^2+y^2 =117

2nd condition

4x-4y=12

÷by 4

x-y=3

x=3+y

Put x =3 +y in 1st

9+6y+2y^2=117

2y^2 + 6y=108

÷by 2

y^2+3y-54=0

By factorization

Y=6

And x=9
