Question

3 The path 1 m wide is tilt along the border inside a sq. garden of side 30m. Find the area of path. The cost of planting the grass in the remaining portion of the garden of the rate of rupees 35 per m2​

Answer 1

Answer:

Let ABCD, the square garden of side= 30 m.

PQRS is the region inside the garden.

so,

PQ = (30 -1-1 ) = 28 m

also

PS = ( 30 – 1 – 1 ) = 28 m

(i) Area of the path = Area of ABCD – Area of PQRS

= [( 30 x 30) – (28 x 28)]

= 900 – 784

= 116 sq.m

(ii) Area of the remaining portion in which the grass is planted = Area of square PQRS

= 28 x 28

= 784 sq.m

cost of planting the grass in the region PQRS = area x cost = 764 x 40

=31,360

Answer 2

Answer:

Cost of planting grass in garden is ₹31,360.

Thank you.
