Question

This is a figure of a rectangular park (Fig 11.1) whose length is 30 m and width is 20 m.
(i) What is the total length of the fence surrounding it? To find the length of the fence we
need to find the perimeter of this park, which is 100 m.
(Check it)
(ii) How much land is occupied by the park? To find the
land occupied by this park we need to find the area of
this park which is 600 square meters (m2) (How?).
(iii) There is a path of one metre width running inside along
the perimeter of the park that has to be cemented.
If 1 bag of cement is required to cement 4 m2 area, how
many bags of cement would be required to construct the

Step-by-step explanation:

Answer 1 = i) = formula of perimeter = 2 * (l + b)

= 2*(30 + 20) = 100

50 = 100/2

50 = 50

50 - 50

0m

ii) area formula = l * b

30 * 20

=600$m^{2}$
