Question

The length of a rectangle is twice the breadth.if peremeter is 60 finds it length

Answer 1

Answer

Let breadth = x

Length = 2x

Perimeter = 2(l+b) = 60

=> 3x = 30

=> x = 10 cm

Length = 20 cm

Answer 2

Answer: Length = 20 cm.

Step by step explanation:

Let the breadth be x, length = 2x.

We know that,

Perimeter of rect. = 2 ( L + B )

60 = 2 ( 2x + x )

60 = 2 × 3x

60 = 6x

x = 10

Thus,

Length = 2x = 2(10) = 20 cm.
