Question

The perimeter of a rectangular pool is 154m . It's length is 2m more than twice it's breadth. what are the length and the breadth of the pool

Answer 1

Hey there ‼
____________________________________

Perimeter of rectangle = 154 cm (given)

Let 'x' be the breadth of rectangle.

So, length of rectangle = 2 + 2x

Now, perimeter of rectangle = 2 ( L + B )

154 = 2 [ ( 2 + 2x ) + x ]

154 / 2 = 2 + 3x

77 = 2 + 3x

3x = 77 – 2

3x = 75

x = 75 / 3

x = 25

Thus, breadth of rectangle is 'x' i.e., 25 cm.
And length of rectangle is 2 + 2x i.e., 2 + 2(25) = 2 + 50 = 52 cm
