Question

5. A square lawn has 3 m wide path surroun-
ding it. Find the area of the path if each side
of square lawn is 50 m. Also find the cost of
cementing the path at the rate of Rs. 7 per m².​

Answer 1

Answer:

side of the inner square =50m

Area = 50^2 = 2500m

side of outer square = 56m

Area = 56^2 =3136m2

Area of the PATH=3136-2500

= 636m2

cost of concenting@Rs 7.

= 636x7=Rs.4452

Answer 2

side of inner square

Area of square =side ×side

=50×50

=2500 m sq

side of outer square=50 +3+3

Area of square= side x side

=56 x56

=3136 m sq

Area of the path = 3136-2500 =636 m sq

cost of cementing =

=636 ×7

Rs.=4452
