Question

if it costs $ 1600 to fence a rectangular park of length 20 m at the rate of $ 25 per m^2 , find the breadth of the park and its perimeter. Also find the area of the field​

Answer 1

Answer:

Step-by-step explanation:

PERIMETER = 2(L+B)

    LENGTH = 20m

  BREADTH = b

Total cost to fence = $1600  

      Cost per meter = 25

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

PERIMETER = 40,000  

NOW WE CAN FIND BREADTH BY DIVIDING PERIMETER AND LENGTH,

BREADTH = 32,000/20

                  = 160

HOPE IT IS HELPFUL !!!
