Question

2) A path of uniform width 1.5 m runs around the inside
a rectangular plot of 80 m long and 60 m wide. Calcule
the area of the path around the plot.​

Answer 1

Step-by-step explanation:

Area of the plot without the path = l x b

= 80 x 60

= 4800 m2

When path is added,

length of park = 80 + 1.5 + 1.5

= 80 + 3

= 83 m

breadth of park = 60 + 1.5 + 1.5

= 60 + 3

= 63 m

Area of park along with the path = l x b

= 83 x 63

= 5229 m2

Area of path = Area of park along with the path - Area of park without the path

= 5229 - 4800

= 429 m2

Answer 2

Answer:

429 m square

Step-by-step explanation:

length of the rectangular plot =80 m

breadth of the rectangular plot = 60m

area of rectangular plot =l*b

80*60

=4800m square

if the path is all around the rectangular plot then it's length and breadth will increase

so length of path =80+1.5+1.5

80+3

83m

breadth =60+1.5+1.5

60+3

63m

area of plot along with path =l*b

83*63

5229m square

hence area of path =5229-4800

492m square
