Question

The length of a rectangle is twice its breadth. Of its perimeter is 48 cm, find the dimensions of the triangle ​

Answer 1

Answer:

Answer is breadth=8 and length=16

Step-by-step explanation:

let the breadth be x

let the length be 2x

perimeter= 2(l+b)

48=2(x+2x)

48=2(3x)

48/2=3x

24=3x

x=24/3

x=8

and length is twice of breadth so

8×2=16

hope it is clear

Answer 2

The relation between the length and breadth of a rectangle is given

length = 2 × breadth

Also, the perimeter of the rectangle is 48 cm

We have to find the length and breadth of the rectangle

perimeter of rectangle = 2 ( length + breadth )

                               48 = 2 {2(breadth) + breadth}

                               24 = 3(breadth)

                     breadth = 24/3

                                   = 8

So, length =  2 × breadth

                 =  2 × 8

                 = 16 cm

Hence, the length and breadth of the rectangle will be 16 cm and 8 cm respectively.
