Question

the length of a rectangle is twice its breadth if its perimeteris 60 cm find the length and the breadthof the rectangle​

Answer 1

Answer:

let the breadth of rectangle = x

Then, length of rectangle = 2x

Perimeter = 60cm

Now, According to ques...

x + 2x = 60

3x = 60

x = 60/3

x = 20

So , breadth of rectangle = 20cm

and, length = 2x = 2(20) = 40cm

Step-by-step explanation:

Answer 2

Let, the breadth be x

the length be 2x

Perimeter = 60cm

ATP

2(2x+x) = 60

=) 4x+2x = 60

=) 6x = 60

=) x = 60/6 = 10

Ans:- Length = (2×10) cm = 20cm

Breadth = 10cm

Additional Information

Perimeter of rectangle = 2(l+b)

Area of rectangle = (l×b)

Perimeter of square = (4×side)

Area of square = (side)²
