Question

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

Answer 1

Answer:

Let the breath = x

so length h = 2x

perimeter of rectangle a = 2(l + b)

60 = 2(2x)

60 = 2 * 3x

60 = 6x

x = 60/6

x = 10

hence, length is 2x = 20 cm

Answer 2

Answer:

Length = 20

Breadth = 10

Step-by-step explanation:

Let the breadth be x

then the length will be 2x

=> 2(l+b) = 60 cm

=>2 ( 2x + x ) = 60 cm

=> 3x = 60 cm ÷ 2

=> x = 30 ÷ 3 cm

=> x = 10 cm

Hence , Length = 2x = 2× 10cm = 20 cm

breadth = x = 10 cm
