Answer:
Perimeter = 400m
Cost of fencing = ₹24000
Step-by-step explanation:
1.
L = 135 m
B = 65 m
Hence, Perimeter
= 2(L+B)
= 2(135+65)
= 2 × 200
= 400 m
Hence, Perimeter is 400 m
Now, rate of fencing = ₹60/m
As perimeter is 400m
Total cost will be
= 400m × ₹60/m
= ₹24000
Answer:
1) ₹24000, 2) 140,80
Step-by-step explanation:
1) length of recatangular plot = 135m
breadth of rectangular plot = 65m
perimeter = 2(l+b) = 2(135+65) = 400m
fencing can be done in outer part of plot so we have to take perimeter to find cost of fencing
cost of fencing= 60/m
so, total cost = 60×400 = ₹24000
2) let the side be x then
length of rectangular field = 7x
breadth of rectangular field= 4x
perimeter= 2(l+b)
= 440= 2(7x+4x)
= 440= 2(11x)
= 440 = 22x
= x = 440/22 = 20 units
therefore, length= 7x = 7×20 = 140 units
therefore, length= 7x = 7×20 = 140 unitsbreadth = 4x = 4×20 = 80 units
