Answer:

length = 6m breadth = 4m and Area = l x b

$\therefore$ Area of carpet is = 6 x 4 = 24 m

Floor area = 960 m

Number of carpets =

Answer: Diagonal (d) = 2.9 m. Let x be the length of each side of the square.

Applying Pythagoras theorem,

$ x^ + x^ = 2x^ = (2.9)^2$

$\Rightarrow x^2 = \text {area of square} = \frac{(2.9)^2}{2} = \frac{8.41}{2} = 4.205 m^2$

Answer: 1 hect = 10000 m2

$\therefore$ 0.5 hec = 5000 m2 $

Applying Pythagoras theorem,

$ \frac{diagonal^2}{2} = 5000$

$\Rightarrow diagonal = \sqrt{10000} = 100 m$

Answer: Diameter of field (d) = 14m

$\Rightarrow r = 14 \div 2 = 7m$

$ \text{Perimeter of semicircle} = (\pi + 2) \times r$

$ \Rightarrow = (\frac{22}{7} + 2) \times 7 = 36m $

Cost of fencing per meter = Rs 10

$\therefore \text{cost of fencing for 36m} = 36 \times 10 = \text{Rs }360$
