ny flower bed 300m² 154 an 키 = 146 m² An acus of a acus of Diameter Conver Ahor A pathway is to be constructed around a rectangular gross lawn measuring 50 m by 30 m- . the width of the path is am Find the area of the path.​

Answer 1

Answer:

the area of path is 936cm²

Answer 2

Answer:

Given, dimensions of rectangular park = 50mx40m

So, Are of park = 50*40 = 2000m²

Area of the grass strip surrounding the pond = 1184 m²

Hence, area of the pond = lb = 2000-1184 = 816m²

Take lengthlength=l and breadth= b

⇒ lb = 816m²

Let the width of the grass strip be 'x'

So, (50-2x)(40-2x) = 816

⇒ 2000 - 100x - 80x + 4x² = 816

⇒ 2000-180x+4x² = 816

⇒4x²-180x+1184 = 0

⇒x²-45x+296 = 0

⇒x²-37x-8x+296=0

⇒x=37, x=8

But x=37 is not possible

∴ Width of the grass strip = 8m

Length of the pond = 50-16 = 34m

Breadth of the pond = 40-16 = 24m
