Question

A path is 1m wide is built along the border and inside a square garden of side 30m
1 Find the area of path
2 Find the cost of planting grass in the remaining portion of the garden at the rate of ₹40 per m​

Answer 1

Solution

Area of the square garden=\left(side\right)^2(side)

2

=30m\times30m=900m^2=30m×30m=900m

2

Length if the garden excluding the path= =30m-2\times1m=28m=30m−2×1m=28m

Area of the garden excluding the path= 28m\times28m=784m^228m×28m=784m

2

(i) Area of the path= 900m^2-784m^2900m

2

−784m

2

=116m^2=116m

2

(ii) Cost of the planting the remaining portion at the rate of Rs 40 per m^2m

2

=Rs\ 40\times784=Rs\ 31,360=Rs 40×784=Rs 31,360
