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

Answer:

it is:

Step-by-step explanation:

x=breadth

2(2x+x)=60

4x+2x=60

6x=60

x=10

length=20cm

breadth=10cm

Answer 2

Let the length and breadth of the rectangle be 2x and z respectively

Perimeter of Rectangle = 2(l + b)

⇒ 60 = 2(2x + x)

⇒ 60 = 2 × 3x

⇒ 60 = 6x

⇒ 60/6 = x

⇒ 10 = x

or x = 10

Length = 2x = 2×10 = 20 cm

Breadth = x = 10cm

Hence length = 20cm and breadth = 10cm
