rate of Rs. 40 per m²



plz give answer fast​

Answer 1

Answer:

Step-by-step explanation:

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
