Answers
Answer:
He needs ₹ 150 to fence the entire field
Step-by-step explanation:
Length of the field = 8m
Breadth " " " = 7 m
Perimeter of rectangle = 2 × (length+breadth)
=> 2 × (7 + 8)
=> 2 × 15
=> 30
Therefore, perimeter of the triangular field = 30 m
Cost of fencing = ₹ 5 per metre
Cost of fencing around his garden = 30 × 5 = ₹150
