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:

Length= 20 cm

Breadth= 10 cm

Step-by-step explanation:

Let breadth be x,

Length= 2x

Perimeter= 60 cm

According to the problem,

2( 2x + x)= 60 cm

4x + 2x= 60cm

6x= 60cm

x= 60/6 cm

x= 10 cm

Therefore, Breadth= x= 10 cm

Length= 2x = 2 × 10 cm = 20 cm

Hope it helps you!!

Answer 2

Answer:

Length is 20 cm and breadth is 10 cm

Step-by-step explanation:

Let breadth to x

then length will 2x

perimeter of rectangal 2(l+b)

=2(x+2x)

=2x+4x=60

6x=60

x=10

x means breadth

and2x means length

length= 20cm

and breadth=10 cm
