Answer 1

Hi there!
Here's the answer:

•°•°•°•°•°<><><<><>><><>°•°•°•°•°

Given„
For a rectangular field,

Length = 34m 20cm
{°•° 1m = 100 cm
=> 20 cm = 0.2m}

•°• Length l= 34 + 0.2 = 34.2 m

breadth = 16m 30 cm
{°•° 1m = 100 cm
=> 30 cm = 0.3m}

•°• Breadth b = 16 + 0.3 = 16.3 m

Now,

(1)

Cost of fencing rectangular field at 41 ₹/m
= 41₹ × perimeter of rectangular field

• Find Perimeter:
Perimeter of rectangle = 2(l+b)
= 2(34.2 + 16.3)
= 101 m

•°• Required cost of fencing = 41₹ × 101 = 4141 ₹

(2)

Cost of turfing the rectangular field at 21₹/m²
= 21₹ × Area of Rectangular field

• Find Area:
Area of Rectangular field = l×b
= 34.2 m × 16.3 m
= 557.46 m²

•°• Required cost turfing = 21₹ × 557.46 = 11706.66 ₹
