Question

The length of a rectangle is twice its breadth. If perimeter is 120 cm. Find length and breadth of
rectangle.​

Answer 1

Step-by-step explanation:

l = 2*b

2*(l+b) = 120

l+b =60

2b+b = 60

b= 20 cm

l= 2*b = 40 cm

Answer 2

Answer:

length=40,breadth=20

• From question:
• length(l)=2×breadth(b)
• perimeter=120
• 2(l+b)=120
• 2(2b+b)=120
• 2×3b=120
• 6b=120
• b=120/6
• b=20..
• and l=2b
• l=2×20
• l=40
