Question

length of rectangle is twice its breadth and its perimeter is 90 cm find the length and breadth ​

Answer 1

Answer:

Length of rectangle = 30 cm

Breadth of rectangle = 15 cm

Step-by-step explanation:

Heya friend,

Here we go:

Let us assume the breadth of the rectangle as 'a'

So, According to question,

length of rectangle = 2 a

Now,

Perimeter of rectangle = 90 cm

and,

Perimeter of rectangle = 2(length + breadth)

So,

2(2a+a) = 90

3a = 90 / 2

3a = 45

a = 15 cm

So,

length = 2a

          = 2(15)

          = 30 cm

So,

Length of rectangle = 30 cm

Breadth of rectangle = 15 cm  

Thanks !

Answer 2

Answer:

Step-by-step explanation:

Let breadth=x

Length=2x

perimeter =90

As per sum

2x+x=90

3x=90

X=90/3 ;x=30

Length=2x=2×30=60

Breadth=x=30
