Question

a triangular garden with sides 20.4m, 63.8m and 48.7 when fencing cost rupees 39.80 per metre ?​

Answer 1

Answer:

SIDES OF TRIANGULAR FIELD ARE 20.4m,63.8m and 48.7m

PERIMETER OF TRIANGULAR FIELD = SUM OF SIDES OF TRIANGULAR FIELD

= 20.4 + 63.8 + 48.7

= 132.9m

COST OF FENCING THE FIELD = PERIMETER OF FIELD × COST OF FENCING 1m square

= 132.9 × 39.80

= 5289.42 rupees

Answer 2

ANSWER:

sides of the triangle=20.4 m , 63.8  m, 48.7 m

perimeter of the triangle=20.4+63.8+48.7

                                          =132.9 m

cost of fencing 1 meter = Rs. 39.80

cost of fencing the triangle=132.9*39.80

                                               =Rs. 5289.42
