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:
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
