Question

a path of uniform width of one and half metre runs around the border of a rectangular garden of 55 M long and 30 M wide slab in a party at the rate of rupees 30 m square​

Answer 1

Length of rectangle with border = 55+1.5=56.5

breadth of rect. with border= 30+1.5 =31.5

Area of rectangle with border = 56.5 x 31.5

= 1779.75

Area of rect. without border= 55x30

= 1650

Area of border= 1779.75-1650

=129.75

cost of laying stone= 129.75x30

=3892.5
