Question

The perimeter of a rectangle is 210 metres and its length is 15 metres more than double the breadth find its length and breadth

Answer 1

Answer:

65 & 30

Step-by-step explanation:

Let breadth be x metre then length = 2x+15

perimeter = 2(l+b) = 2(2x+15+x) = 6x+30

given perimeter = 210

6x+30 = 210

6x = 180

x = 30

Length = 2x+15 = 65 metre

Breadth = x = 30 metre
