Answer 1

Answer:

Area of the path=Area of outer square-Area of inner Square

= 21^2-15^2 = 36x6=216m2

cost of cementing @ Rs 7 =

216x7=Rs.I5I2. Ans

Answer 2

The area of the path is 216 sq.m,. and the cost of cementing the path is Rs.1512

Step-by-step explanation:

Side of square lawn = 15 m

A square lawn has 3 metre wide path surrounding it

So, Outer length = 15+(3+3)=21 m

Area of path = Outer area -Inner area

Area of path =$(21)^2-(15)^2$

Area of path =$216 m^2$

Cost of cementing 1 sq.m. path =Rs.7

Cost of cementing 216 sq.m. path =$216 \times 7=Rs. 1512$

Hence the area of the path is 216 sq.m,. and the cost of cementing the path is Rs.1512
