Answer:

12 cm

Step-by-step explanation:

he will use the rectangle formula

Answer 2

Answer:

length = 12

Step-by-step explanation:

perimeter of rectangle= 2(l+b)=x

perimeter of square =twice of rectangle

so we can take = 2x

perimeter of square = 60cm

". ". rectangle= 2x= 2(l+b)

= 60/2 =2(l+3)

= 30=. 2l+6

= 2l+6=30

=. 2L= 30-6

=. L = 24/2

=. L= 12
