Requiredanswer:

GiveN:

Length of a rectangle is 8m less than twice its breadth.

Perimeter of the rectangle is 56 m

To Find:

Length and breadth of the rectangle...?

Step-wise-Step Explanation:

According to Question, the length may be greater or less than the breadth. For convenience, let the breadth be x.

⇒ Length = 2(Breadth) + 8

⇒ Length = 2x - 8

Now we can find the perimeter of the rectangle by using the formula. But the perimeter given is 56 m.

Perimeter = 2(Length + Breadth)

Putting the values of length and breadth,

⇒ P = 2(l + b)

⇒ 56 = 2(2x - 8 + x)

⇒ 56 = 2(3x - 8)

⇒ 3x - 8 = 28 m

⇒ 3x = 36 m

⇒ x = 12 m

Then the length and breadth of the rectangle:

Length = 2x - 8 = 16 m

Breadth = 12 m

And we are done!
