Answer 1

Hope its helpful Give me thanks Mark me branliest

Answer 2

Answer:

Now, first perimeter = 15

let breath be y

let length be x .

Now perimeter of rectangle = 2(l+b)

15=2(x+y) ---- 1 eq

15/2-y = x

7.5+y = x

by eq.. 1

15 = 2(7.5+y+y)

7.5 =7.5+2y

7.5-7.5= 2y

1/2=y

0.5=y

15=2(x+0.5)

7.5 = x+0.5

x =7

Hence, y=0.5,x=7
