from a number and multiply the result by you get
154 m. Its length is 2 m more than​

Answer 1

Answer:

let breadth of the rectangular swimming pool be x m.

and length be 2x +2 m .

since, perimeter of rectangular pool = 154m.

2 (2x + 2+ x) m = 154 m

Or, 4x + 4 + 2x = 154 m

Or, 6x = 154 m - 4

Or, 6x = 15o m

Or, x = 150/6 m

x = 25 n

so , breadth of rectangular swimming pool = x = 25m

Therefore, length = 2x + 2 = 2 × 25 + 2

= 50+2 = 52 m
