Question

The length of a rectangular plot is twice it's breadth. If its perimeter is 30 m, then its length and breadth will be?​

Answer 1

Answer:

Length = 10 m

Breadth = 5 m

Answer

Answer 2

⛦ Given :

• Length of rectangular plot is twice its breadth
• Perimeter of rectangle = 30 m

⛦ To find :

• The Length
• The Breadth

⛦ Solution :

Let's consider the Breadth of the rectangle as x

Then the Length will be 2(x) = 2x

Now,

According to Question,

Perimeter of rectangle = 2(l + b)

30 = 2(2x + x)

30 = 2(3x)

30 = 2 × 3x

30 = 6x

x = 30/6

x = 5

Therefore,

• Length of rectangle (2x) = 2×5 = 10cm
• Breadth of rectangle (x) = 5 cm

Check :—

Perimeter of rectangle = 2(l+b)

Putting the values.

⟼ 30 = 2(10 + 5)

⟼ 30 = 2(15)

⟼ 30 = 2 × 15

⟼ 30 = 30

Thus, both the sides the value are equal.

Thus, checked!!
