Answer:

length of rectangle will be 20 cm

Step-by-step explanation:

if s side of square is 15 cm so the. perimeter will be 60cm ( 15 ×4)

so the perimeter of rectangle will also be 60cm

perimeter of rectangle =2×(l+b)

breadth = 10

2× 10=20

60-20=40

so other side would be 40÷2= 20

Answer:

Length = 20

Step-by-step explanation:

\bf{\huge\mathcal{\boxed{\rm{\mathfrak\blue{Hey Mate:}}}}}

Case 1 :

Perimeter of Square = 4×15 = 60 cm

Case 2 :

Let the length be 'y'

Perimeter of rectangle = 2y + 20

In both cases, perimeters will be equal, so :

2y + 20 = 60

y = 20
