Question

The length of a rectangle is twice its breadth. If its perimeter is 60 cm, find the length

and the breadth of the rectangle.​

Answer 1

Step-by-step explanation:

Let breadth be x

Length =2x

Perimeter =2(l+b)

60=2(2x+x)

30=3x

x=10=b

l=2×10=20

Answer 2

★ Question :-

The length of a rectangle is twice its breadth. If its perimeter is 60 cm, find the length and the breadth of the rectangle.

⠀⠀⠀⠀⠀⠀⠀

★ Answer :-

⠀⠀⠀⠀⠀⠀⠀

✠ Given :-

• The Length of a rectangle is twice as its Breadth .
• Perimeter of Rectangle = 60 cm

⠀⠀⠀⠀⠀⠀⠀

✠ To Find :-

• The length and breadth ?

⠀⠀⠀⠀⠀⠀⠀

✠ Solution :-

⠀⠀⠀⠀⠀⠀⠀

∓ We have to calculate the Lenght and Breadth of the Rectangle .

• Let Breadth be x cm .
• And Length will be 2x cm .

⠀⠀⠀⠀⠀⠀⠀

✪ Perimeter of Rectangle = 2 × [ L + B ]

➠ 60 = 2 × [ L + B ]

➠ 60 = 2 × [ 2x + x ]

➠ 60 = 2 × [ 3x ]

➠ 60 = 6x

➠ x = 60 / 6

➠ x = 10

⠀⠀⠀⠀⠀⠀⠀

★ Hence :-

• The Breath = 10 cm
• The Length = 10 × 2 = 20 cm
