Answer 1

Step-by-step explanation:

perimeter of the rectangle is 2(l+b)

area of rectangle is. l×b

Answer 2

Answer:

• Perimeter of rectangular field = cost of fencing÷rate of fencing
• P=4800÷60= 80m
• Now length is given 13m
• Then
• Breadth= perimeter -length÷2
• B=80- 13÷2= 73.5m
• Area of the rectangular field =length×breath
• Area=73.5×13=9555.8square metre
