Answer 2

Answer:

231.2

Step-by-step explanation:

PERIMETER = 2(L+B)

    LENGTH = 25m

  BREADTH = b

Total cost of building = ₹680  

          Cost per meter = 8.50

TO FIND PERIMETER WE HAVE TO MULTIPLY BOTH TOTAL COST OF BUILDING AND COST PER METER,

PERIMETER = 5780

NOW WE CAN FIND BREADTH BY DIVIDING PERIMETER AND LENGTH,

BREADTH = 5780/25

                 = 231.2

HOPE IT IS HELPFUL !!!
