Question

The perimeter of rectangular swimming pool is 154m. It's length is 2m more than twice it's breadth of the pool?

Answer 1

Answer:

Breadth = 25 m

Length = 52 m

Step-by-step explanation:

Let the breadth be x

Length = 2x + 2

Perimeter = 2(l+b) = 154 m

= 2[2x+2+x] = 154

= 2[3x+2] = 154

=3x + 2 = $\frac{154}{2}$

= 3x + 2 = 77

= 3x = 77 - 2

= 3x = 75

= x = $\frac{75}{3}$

= x = 25

∴ Breadth = 25 m

  Length = 2x + 2 = 50 + 2

               = 52 m
